The singer looked like he enjoyed himself during today's draw broadcast live on television
It's well known the Rod Stewart is a Celtic fan and overall an avid follower of football in general.
The rock sensation is often pictured at games in Scotland and was even at the Old Firm derby last September when Celtic thumped fierce rivals Rangers 5-1.
On Sunday, the 72-year-old appeared in fine form during the televised Scottish Cup draw and even snubbed a handshake from SFA president, Alan McRae.
Live on Sky Sports, the broadcaster noted "Stewart stole the show with his enthusiasm and excitement as he picked Celtic to face Inverness".
Always the showman, Stewart did his best to accentuate every hand movement and amplified the delivery of each of the ball's numbers throughout.
