Doting mother Jackie 'O' Henderson takes her daughter Kitty, 13, to Olivia Rodrigo's second Sydney Guts show

Jackie 'O' Henderson proved herself to be every inch the doting mother as she took her daughter Kitty to watch Olivia Rodrigo on Friday night.

The radio host, 49, took to her Instagram Stories to document their mother-daughter night out at the Qudos Bank Arena for Olivia's second Sydney show on her Guts tour.

She shared an array of selfies of herself and Kitty, 13, who she shares with her ex-husband Lee Henderson, as they sat in the crowds at the 21,000-capacity venue.

For the occasion, Jackie looked effortlessly stylish in a blue and red T-shirt and showed off her stunning features with a natural make-up palette.

She flashed a huge smile as she sweetly wrapped her arms around Kitty, who looked delighted to be watching American pop star Olivia, 21, perform live.

Olivia is currently Down Under for the Australian leg of her Guts tour and had already put on four incredible shows in Melbourne before coming to Sydney.

In Sydney, she performed on Thursday and Friday nights and has two final shows remaining on her Aussie tour on Monday and Tuesday.

However, she suffered a faux-pas during her first Sydney show as a cheeky request she made of two fans hilariously backfired.

In footage shared to social media, the Deja Vu hitmaker asked two of her fans to share a smooch for the cameras in a 'kiss-cam' style interaction.

However, she didn't realise the pair were actually brother and sister and was left red-faced at her unfortunate request.

'You guys are so cute! I have a huge and fun favour to ask, would you guys give us a kiss on the Guts cam?' Olivia asked the siblings.

The pair then told Olivia they were not a couple, but in fact siblings, leading the singer to hold up her hands in shock.

'She's your sister! Oh s**t, never mind, scrap that! F**k, wow, that hasn't happened before,' an embarrassed Olivia screamed out, asking her crew to quickly cut the footage.

'This is the first time! Wow, I feel really bad now, we are going to forget that ever happened!' Olivia joked.

Olivia has been crowned an honorary Aussie after immersing herself in local culture since arriving Down Under.

The energetic performer has been wholeheartedly embracing all things Australian while on tour, and her fans are loving every moment of it .

Olivia has professed her love of Aussie snacks and local tourist spots and recently indulged in an iconic treat.

After sampling some Tim Tams last week, Olivia continued her culinary adventure Down Under, sharing a snap on social media of a stash of Caramello Koala chocolates.
