After all, nothing says it's your birthday like a slew of cringe-worthy photos from old albums, right?
Taking to Instagram, Arg chose to mark Lydia's 25th birthday (who she actually shares with his best pal Mark Wright) with an hilarious photo from their younger years.
The couple - who have been dating for over seven years now - first met back when they were teenagers, so you can imagine the snaps they have hidden away. Yup, a box full of gems.
Arg chose one of himself and Lydia posing together, with him rocking a questionable haircut and Lydia sporting one very deep fake tan. It's safe to say the couple have since blossomed!
Alongside his throwback, he paid a touching tribute to his other half. Arg gushed: "Happy Birthday to my Best Friend, Lover & Soul Mate @lydiabright Gutted I'm away from home, love & miss you so much! Many more Bdays to celebrate together! 143 from Your Arg x."
Lydia, meanwhile, was loving being the birthday girl. She told her followers on the photo-sharing app: "It's my birthday, it's my birthday, 25 today!! I'm officially 1/4 of a century. Do I still count as young?? So grateful for all my beautiful friends and family. Feel very blessed for another FABULOUS year!!!"
While Arg was around for Lydia's birthday party over the weekend, he has had to miss spending her actual birthday with her due to training for The Jump.
Earlier this month, Arg confirmed he will be taking part in Channel 4's winter sports competition, despite never having skied before. He joins the likes of Rebecca Adlington, Sarah Harding and Brian McFadden.
Hoping to hone his skills before his debut, Arg is currently in Austria mastering the slopes and he's been bonding with Made In Chelsea's Mark-Francis Vandelli while away. The 28-year-old told fans Mark is his new bestie!
Lydia, meanwhile, recently admitted to Reveal she was going to miss Arg while he was away - but she was incredibly proud of him for taking on the show.
"It will be hard because we haven't had loads and loads of time together," she exclusively told us. "When there's distance between you and you're not together every night, it is sometimes hard, but then when you do see other, it's really special... They say absence makes the heart grow fonder and I think it does."
She did add, though: "I am nervous... I'm just hoping he doesn't go out there and hurt himself... I just don't want him coming back with any broken bones. That's all I'll ask of him!"
