Girls trip! Jackie ‘O’ Henderson cuts a casual cool figure as she jets off to Europe with her bestie Gemma O’Neill

Jackie ‘O’ Henderson has jetted off on a working holiday to Europe with her best friend and podcast co-host Gemma O’Neill.

The pair departed Sydney Airport on Monday for the trip, which will see them visit Berlin and Athens.

Jackie was dressed comfortably for the flight, wearing a plain black P.E Nation T-shirt.

She also wore a pair of dark-coloured camouflage cargo pants and white Adidas sneakers.

The KIIS FM star finished her flying attire with a pair of black wayfarer-style Ray-Ban sunglasses.

She wore minimal makeup and had her blonde locks in a natural straight style for the flight. 

Keeping the accessories to a minimum, Jackie was spotted wheeling two large grey suitcase with one carrying a black puffer jacket.

Meanwhile, Gemma also went casual in a plain white T-shirt under a black sports jacket with dark blue jeans and white sneakers.

Lugging a pink suitcase, Gemma also carried a large grey overcoat in the crook of her arm and a light brown leather bag.

The pair looked chuffed to be jetting off together, with Jackie sporting a huge grin after the pair were farewelled a pal.

Prior to her flight, Jackie also shared some clips to her Instagram story that showed the excited besties preparing to board.

‘Only six months ago I was crying on a plane saying: “We’re never going to have another girl’s trip, and here we are,’ Gemma said to Jackie as they walked through the airport.

Jackie added: ‘Here we are. We are going to Berlin and then to Athens. We’ve never been to either, so another girl’s trip, here we come.’

Gemma jumped in to remind followers that their trip was strictly professional.

‘It is a work trip though, I should point out. We’ll have some fun along the way,’ she said. 

‘Berlin’s not. Berlin’s a holiday,’ Jackie added and told her fans that the pair would check in later.

Her bestie replied with a cheeky: ‘I’ll be drunk.’

‘She will be, you know. ‘Lucky you.’ Jackie replied.

If the couple’s past overseas jaunts are anything to go by, Jackie and Gemma are in for quite the time.

Back in October, Jackie revealed on their Your Best Life podcast that a previous trip together resulted in Jackie having a romantic dalliance with a mystery man. 

The pair were discussing relationships when Jackie spilled the beans on a one night stand Gemma experienced while the pair were holidaying in Greece.

‘I’m thinking that I should go on a date because I haven’t had any flirtation stuff for ages,’ Gemma admitted, before Jackie questioned the validity of her claim.

‘Define ages,’ Jackie replied. 

‘There was Greece…the one night stand.’

A clearly shocked Gemma replied with ‘That was not to be said on a podcast.’

Gemma revealed the fleeting interlude was her first one night stand, which also forced Jackie to admit that she, too, had recently had taken part in a no-strings-attached fling.

‘I’ve only just had a one night stand not that long ago to be honest, my first as well,’ Jackie admitted while remaining coy about the details.

The frank admissions didn’t stop their either after Gemma threw Jackie ‘under the bus’ regarding a steamy encounter with a mystery man while on the Greek trip.

‘If you’re going to throw me under the bus in Greece, I’m going to throw you under the bus too. because whilst I was meeting this guy, you were pashing a guy on the beach,’ she said.

Jackie confirmed Gemma’s claim, adding she only decided to seek out a romantic encounter as she was feeling bored.

‘We’re at this club in Mykonos, a very famous club called Scorpios and Gemma’s getting with this guy, like really hitting it off. You know like when you’re friends hitting it off with a guy and they’re in their own bubble?’ Jackie explained.

‘I just was standing there like a third wheel, I didn’t know anyone else and I thought: Oh, s**t I’m bored what am I going to do?’

Jackie added it did not take too long for her to find a suitable suitor to help her ‘kill time’.

‘So, I went in search of someone I could pash and I found an Israeli accountant,’ she said, laughing.

‘He was really cute, so I pashed him. I killed time, but I didn’t sleep with him or anything.’

Gemma said the scene made her feel like she was a teenager again.

‘There was a moment when I was pashing my guy and I saw you pashing your guy and I felt like we were 17 at the high school dance,’ she quipped.
