Leonardo DiCaprio and girlfriend Vittoria Ceretti enjoy Mexican getaway with his mom for star's 50th birthday

Leonardo DiCaprio and girlfriend, Vittoria Ceretti, whisked themselves away to Mexico for a lavish getaway to celebrate the star's 50th birthday.

The Oscar winner, 50 - who had a blast during a star-studded birthday bash over the past weekend - was seen boarding a private jet in Los Angeles on Monday with the Italian model, 26, and his mother Irmelin.

DiCaprio kept it casual for the busy day of travel in a pair of black sweatpants as well as a black, hooded sweatshirt that was partially zipped up at the front.

The actor additionally wore a printed, white shirt underneath and added a black cap on top of his head.

Leonardo slipped into a pair of comfy, gray sneakers that were secured with laces and carried a black backpack over his shoulders.

Vittoria - who was first romantically linked to DiCaprio in August 2023 - also dressed down in vibrant, green and yellow sweats.

The beauty's dark locks were pulled back into a sleek bun to prevent loose strands from falling onto her face.

Ceretti opted for minimal accessories and added a pair of mini earrings as well as fashionable shades for a finishing touch.

The model easily carried a large, black bag over her right shoulder to hold items she needed while on the plane.

Leonardo's mother, Irmelin, donned a pair of loose-fitting trousers as well as a white shirt and blue sweater that was wrapped around her waist.

The group was spotted making their way towards a private jet in Los Angeles and were later seen once again after touching down in Mexico.

DiCaprio officially celebrated his 50th birthday on Monday - and over the weekend, had the chance to ring in the milestone with close friends.

On Saturday, the Inception actor was joined by 500 guests at a private estate in the Hollywood Hills where a lavish party was held.

Some of the A-list celebrities that were in attendance during the special night included Brad Pitt, Katy Perry and Paris Hilton.

To keep the party private, guests were given stickers to cover up the cameras on their phones upon arrival.

Earlier in the night, the Baby2Baby Gala took place in Los Angeles - and numerous stars made their way to Leonardo's birthday bash afterwards, per Page Six.

A source explained to the publication that, 'Basically, the Baby2Baby group all went to Leo's after.'

Stars had the chance to dance to DJ Meel's set and the insider stated that he, 'spun late into the night.'

Aside from the music, celebrities also had the chance to indulge in glasses of Telmont champagne as well as sugary cake.

And hours later on Sunday, DiCaprio was accompanied by Vittoria and other close pals such as Tobey Maguire, Joel Edgerton and Evan Ross for a birthday dinner at Stella Ristorante in West Hollywood.

After grabbing a bite to eat at the hotspot, the group was seen standing outside of the eatery and shared embraces before parting ways for the night.

Leonardo opted for an all-black ensemble that comprised of black pants as well as a black shirt and jacket.

Vittoria put on a stylish display wearing a pair of denim shorts which were paired with an oversized, black blazer.

The Italian supermodel additionally donned a black and white-striped top and slipped into a pair of black boots.

Shortly before the Oscar winner celebrated his 50th birthday, a source informed Us Weekly that DiCaprio and Ceretti were still going strong ahead of the festivities.

'They have a lot of respect for each other. They both travel a lot for work and are very supportive of each other's careers.'

However, another insider explained that the Titanic actor isn't ready to settle down just yet, and told the outlet, 'He just doesn't see the point in settling down.'

Leonardo and Vittoria first crossed paths at the Cannes Film Festival in May 2023 and three months later in August, sparked romance rumors when they were seen on an ice cream date in Santa Barbara, California.

The next month, the Hollywood star flew to Milan for fashion week where Ceretti was walking the runway.

The pair also celebrated Leo's 49th birthday last year in November together - and that same month, their relationship was confirmed.

At the time, a source told Us Weekly that DiCaprio was 'completely smitten' with the model and added, 'It's going so well that Leo's actually being exclusive.'

'He says she's not only gorgeous, but super down-to-earth, and they have a ton in common.'

The insider added, 'She's not intimidated by his fame at all - she even makes fun of it, "the model and the movie star." Leo finds it refreshing.'

In regards to their age gap, the source explained that it 'clearly isn't an issue for him' while adding that Ceretti 'is an old soul.'

The actor's close friends are also 'keeping their fingers crossed that Leo may have finally found The One,' the insider added.

Before his 50th birthday, the lovebirds were seen together as they attended Kendall and Kylie Jenner's Halloween party.

It came shortly after Leonardo was seen hanging out with Teyana Taylor as they partied together in NYC until 3a.m. last month in October.
