Sir Rod Stewart leaves fans giggling as he shares hilarious video of backstage warm-up routine

Sir Rod Stewart has left fans giggling after he shared his backstage pre-gig warm-up routine as he continues his The Hits! tour in America.

The 'Maggie May' singer took to social media to give his followers a behind-the-scenes glimpse of how he gets ready to go on stage and perform.

And his pre-concert antics are hilarious!

In the video, the music legend can be seen being handed his earpiece before he starts to stretch his legs and jump around.

He captioned the video: "Ever wondered about my pre-gig warm-up? Always time to get limber for you lot."

But while fans loved the 77-year-old's pre-show antics, it seems he didn't amuse everyone, as a crew member was captured in the background looking far from pleased while holding Stewart's microphone.

One fan commented: "The guy in the background watching him."

Another said: "Chap behind you not looking too impressed."

Stewart continues his North American tour with performances in Massachusetts, New Jersey and Florida among other states this month.
