Olivia Culpo has sparked rumours she's back together with Danny Amendola.

The former Miss Universe - who previously dated Nick Jonas - split from the NFL player back in March following nearly two years of dating, but it looks like the pair have managed to work through their issues as they attended a wedding together in Houston over the weekend after the hunk invited the model as his date.

A source told TMZ: ''They were doing lots of kissing, hugging, and hand-holding.''

The 26-year-old beauty was clearly cut up about their split when they decided to go their separate ways as she admitted at the time that she couldn't talk about it.

She said: ''It's just so fresh for me, I don't feel comfortable talking about it. Everybody goes through breakups in life. Everybody has their own way of handling it.''

But Olivia is no stranger to dealing with break ups in the public eye as her former flame Nick was pretty hurt when they ended their relationship three years ago.

He said at the time: ''I haven't heard from her in a year.

''I don't know if I'll hear from her again. I'm not sure.''

However, Olivia inspired a number of tracks on his latest album 'Last Year Was Complicated', and he often wonders if she has heard the song 'Champagne Problems' which details what went wrong in their relationship.

He said: ''I've thought a lot about whether she's heard it, and I'm sure she's heard 'Champagne Problems' at this point.

''The concept of the song, which maybe doesn't stand out on first listen, is, 'You're amazing, you're all the things I hope to find with somebody, but timing, circumstances, all these things play into it not being right.' Champagne is amazing; it tastes delicious but gives you a really bad hangover. That's the idea...''
