Life Loves of the Cast of 'Shark Tank'

Behind every shark on Shark Tank are the husbands and wives who are in the tank for Mark Cuban , Kevin O'Leary , Lori Greiner , Barbara Corcoran and Daymond John .

Shark Tank, which first premiered in 2009, offers some of America's most creative and innovative entrepreneurs the chance to give their businesses a financial boost by pitching their ideas to the "sharks," who not only can take the chance to invest, but also to help mentor and bring awareness to the companies they back.

Over the years, Shark Tank has brought companies and products such as Scrub Daddy, Grace and Lace, Manscaped, Bombas Socks, Lovepop and more to the masses.

Sixteen years and millions invested later, Mark Cuban, who's been on the show since its inception, announced that this season will be his last .

Simultaneously, the show is also welcoming Daniel Lubetzky as a regular investor — the first addition in over 10 years, per Variety .

As we gear up for the season 16 premiere of Shark Tank on ABC tonight, see the real-life loves of your favorite investors.

of 07 Mark Cuban's Wife Tiffany Stewart Billionaire Mark Cuban has invested in companies such as Chirps, Simple Sugars, Dude Wipes, Truffle Shuffle and more during his tenure on the show.

When he's not wheeling and dealing, the warm-hearted investor has been married to wife Tiffany Cuban (née Stewart) since 2002.

According to a Forbes interview from 2000, Mark met Tiffany, who worked in sales at an advertising agency, at the gym in 1997. But beyond that, the future Dallas Mavericks owner was tight-lipped about his relationship and not much has changed in that regard. While his profile has risen significantly, Tiffany, along with their three kids — Alexis Sofia, Alyssa and Jake — stay relatively out of the spotlight.

of 07 Barbara Corcoran's Husband, Bill Higgins, When she's not making everyone laugh with her undeniable humor in the tank, Barbara Corcoran brings the comedy routine home to her husband, Bill Higgins .

The real estate mogul met the former navy captain and FBI agent at a conference in 1981.

"What I thought I wanted when I married Bill 35 years ago was an exciting, sexy guy to travel the world with," she wrote in an Instagram post back in 2020. "Now long into our marriage, I realize I've got the important stuff. A rock solid guy, a close friend, and a great father to our children."

Corcoran and Higgins welcomed two children : son Tom in 1993 and daughter Kate in 2005.

of 07 Daymond John's Wife, Heather Taras Daymond John knows how to seal the deal in the shark tank and he showed that when he proposed to his longtime love Heather Taras during a live taping of the show in 2016.

Though the proposal never aired on television, John says it was nerve-wracking.

"I was nervous I was proposing on set, but, really because, you know, my fiancée [and I have] been together for many years, and she knows all the sharks. So I saw Kevin in the corner whispering to her about royalties and all kind of stuff when I proposed," John told Harry Connick Jr. in 2017 on Connick's talk show .

But despite O'Leary's attempts to counsel her financially, "She said, 'Yes,' and I'm very happy about that," John shared.

The couple wed in front of family and friends at John's childhood church in Queens, New York in 2018.

John and Taras share daughter Minka Jagger, whom they welcomed on March 2, 2016. John also has two daughters — Yasmeen and Destiny — from a previous relationship.

of 07 Kevin O'Leary's Wife Linda O'Leary Long before Kevin O'Leary was known to us as Mr. Wonderful, he had already found his Mrs. Wonderful.

Kevin married Linda O'Leary on March 17, 1990. And while the businessman is known for his love of the finer things in life, their wedding, which took place at their home, was very low-key.

"I said to my wife, 'Why go in debt?' Let's invite our friends over, let's buy a few cases of beer and I'll order some pizza," Kevin told CNBC Make It in 2018. "We saved a fortune. I was able to put it in my business to start growing it."

Kevin and Linda welcomed their first child, daughter Savannah, on Feb. 18, 1993. Three years later, they welcomed son, Trevor, on Sept. 22, 1996.

of 07 Lori Greiner's Husband Dan Greiner Lori Grenier keeps her marriage to Dan Greiner so under lock and key, there aren't any publicly available pictures of the pair.

Still, Dan has stood firmly by his entrepreneurial wife throughout their marriage. Not only did he support Lori's first invention — a jewelry organizer — but he was an active partner in its success, sketching it out, partnering with her to take out a loan to create it and then helping her market it.

"He's cautious – not at all the type to push the envelope," Lori wrote in her book, per Country Living . "And yet, in this instance he was on board from the minute I told him about my idea."

Once her first invention gained success around 1996, Dan left his job and began working for her company, For Your Ease Only, Inc. In the years that followed, Dan has been the "Owner, CFO, COO, Founder" of Lori Greiner Companies.

of 07 Robert Herjavec's Wife, Kym Johnson Beloved for his adventurous spirit and the fact that he will try anything in the tank — scooters, ice baths, silly costumes, you name it — Robert Herjavec was already well-established when he met former Dancing with the Stars pro, Kym Johnson .

The pair fell in love when they were partnered during season 20 of the dance competition.

"We were friends first, and we got to know each other on a friendship level; I think that's really important," the dancer told PEOPLE several months after the two began dating. "That developed into something else, and it's really great. We're both each other's number one fans, and have respect for each other."

The two got engaged and wed in 2016. They welcomed twins Haven Mae and Hudson Robert Herjavec on April 23, 2018.

of 07 Daniel Lubetzky's Wife, Michelle Lynn Liebermann Kind Bar founder Daniel Lubetzky joins Shark Tank as a full-time shark this season.

Lubetzky married his wife, Michelle Lynn Leiberman in March 2008. According to the New York Times , the couple tied the knot in a civil service held in San Antonio, Texas before holding a religious ceremony in Mexico.

At the time, Leiberman was completing her residency in internal medicine at New York-Presbyterian/ Weill Cornell Hospital and is now a physician.

Lubetzky and Liebermann have four children whose identities they keep under wraps.
