Jason Derulo is getting pumped before hitting the stage in Glasgow tomorrow - by hitting the gym.

The American singer was spotted working out at The Gym on Bothwell Street earlier this evening.

Derulo is in the city ahead of his SSE Hydro show on Saturday night.

The Talk Dirty hitmaker was seen lifting weights surrounded by an entourage at the city centre gym.

Fellow gym-goer Ross Reilly spotted the megastar and posted a snap on social media.

He said: Jason Derulo is in ma gym in town, full squad with him."

He's not the only superstar to be spotted out and about in Glasgow this week as Shania Twain enjoyed dinner at Buck's Bar earlier in the week.
