Colton Haynes and Jeff Leatham have sparked speculation they could get back together after reuniting to celebrate the 'Teen Wolf' star's birthday. 

The 30-year-old actor filed for divorce from the celebrity florist in May, just seven months after they married in October last year, but they have fuelled rumours that they may reconcile for good after they were spotted at Los Angeles International Airport. 

A source said: "Colton and Jeff got off a flight together at LAX. They were returning from Vancouver where they celebrated Colton's birthday over the weekend."

Colton - who turned 30 last Friday - and the floral designer were spotted walking together through the airport's terminal. 

The source added to E!: "Colton is filming 'Arrow' and Jeff was visiting him. It definitely seemed like they had reunited at least for the weekend."

This comes just two months after the 'San Andreas' star filed divorce documents in Los Angeles, just half a year after their star-studded wedding in Palm Springs, which was officiated by Kris Jenner.

Colton previously took to Twitter to slam speculation that Jeff could've been unfaithful to him. 

He wrote: "Jeff would never cheat. He is an amazing man. Please stop being mean to him."

In November, Colton shared an "emotional but beautiful" clip of the former couple's big day on his YouTube channel.

Writing in the description of the professionally filmed video, he said: "This video makes me cry every single time i watch it. It was the most special day of my life and we wanted to share a little bit of it with y'all. I don't know what I'm gonna do when i see the whole video lol but I really want to thank the incredible team of photographers & videographers that helped capture such a special moment.

"HOPE YALL ENJOY & CRY HAPPY TEARS :) More to come & can't wait to share more stories of our special day :) Love you Jeff & to everyone supporting us on this magical journey :) (sic)"
