They are set to marry in November this year, after an engagement earlier this year.
And it seems the honeymoon period definitely isn’t over for Paris Hilton and her fiance Chris Zylka, as they put on an intimate display during the de Grisogono party in Cannes.
The loved-up couple only had eyes for each other as they smooched at the glitzy event, hosted by the jewellers on Tuesday evening.
Paris, 37, turned heads in an extremely low-cut gown which was also split up to her thigh, putting her lithe limbs firmly on display.
The socialite’s show stopping dress glittered in purple hues as she posed dramatically at the swanky event.
Not one to blend into the background, Paris teamed her dress with a fluffy blue boa and a pair of bejewelled stilettos.
The heiress wore her blonde locks in a straight, sleek style while adding yet more sparkle to her dazzling ensemble, with a diamond watch and her jaw-dropping engagement ring.
Her beau Chris kept his look sharp in a black suit with satin lapels, however the actor added a splash of colour to his outfit in the form of some red shoe laces.
Paris and Chris are set to tie the knot November 11, family insiders told DailyMail.com exclusively.
The source said said: ‘No one is quite sure of the significance of the “11/11” wedding date, but that’s what they’ve chosen.
‘It’s on a Sunday, but following day is a holiday (Veteran’s Day) so it will be a long weekend celebration.’
The pair have already visited the church to meet with the priest who will officiate their wedding, The Blast reported.
After previously gushing about her dream Disney-inspired gown, Paris has revealed she found the perfect dress to wear as she walks down the aisle.
She said: ‘I did pick the final one! It is so iconic and I can’t wait for everyone to see. Right now we’re custom making it so it is going to be really special. We looked at a lot of different options because I am friends with so many incredible designers who are so talented. So it was a really hard choice!’
The DJ plans to keep the details of her gown under wraps until her big day.
Paris however has shared some inside knowledge into an after party outfit that she’s working on with Moschino creative director Jeremy Scott.
She told People magazine: ‘Jeremy Scott and I were talking about the after party look because he has just been my friend since I was a teenager and he would make the perfect after party dress. So that is one little hint I’ll give! I’m friends with too many designers. Everyone wants to be a part of [my wedding].’
The end of Paris’ dress hunt comes after she previously revealed she wanted an extravagant dress.
Paris said she was inspired by Disney’s beloved animated characters, who include Ariel from The Little Mermaid, Belle from Beauty And The Beast and Rapunzel from Tangled.
She said: ‘It’s a lot of planning to do. Right now, we are just trying to figure out a date and a location and my dress. I definitely want it to be very magical. I love Disney princess vibes.’
Now that one big decision is out of the way, Paris can start focusing on her guest list for the nuptials, as she admitted she still isn’t sure who to invite and is considering having multiple receptions with the different groups of people she knows.
She said: ‘I have so many friends and it’s so hard to pick. I have all my mom’s friends, all my family, all my cousins and all of that and then I have my other group of friends who are like my fun friends who I’m at Coachella with and EDC and Burning Man. It’s going to be a very weird mixture to have everyone, so I don’t know. Maybe I do like the family wedding and then the fun, friend wedding – the after, after party wedding.’
The Simple Life star announced their engagement in January.
