'Married at First Sight' star Ryan Gallagher shares video of Jo McPharlin riding mechanical bull

Married at First Sight (MAFS) reality star Ryan Gallagher has shared a series of hilarious videos featuring Jo McPharlin attempting to ride a mechanical bull and falling off.

Posting the clip to his Instagram story, the video shows his MAFS co-star, 39-year-old McPharlin, riding the bull for several seconds before she is flung off sideways into the cushioned ring.

In what appears to be a mini cast reunion, Gallagher, 29, pans to McPharlin's ex-TV husband Sean Donners as he shouts to a laughing Donners, "You're still in love Sean, you're still in love!"

Another video follows McPharlin shaking her head and laughing while walking away from Donners as she says "no." Meanwhile Gallagher continues to tease them in the background shouting "Still in love, still in love!"

Having recently bared it all for NW, it seems that the single tradie is as jocular as ever and isn't letting his former flame and on-screen wife Davina Rankin keep him down.
