HOLLYWOOD star Jon Hamm was spotted in the crowd at Celtic Park last night - and excited fans have reacted.  

The Mad Men star, 50, was pictured taking time off his filming schedule for Good Omens to watch the bhoys play Hibernian.

Jon was sitting near St Mirren manager Jim Goodwin and Hibs players Paul McGinn and Ryan Porteous. 

Fans responded to the sighting on Twitter, with one commenting: "Jon Hamm what a boy", while another wrote that they were "hyperventilating" at the picture.

One Celtic and Mad Men fan said: "Great seeing Jon Hamm at the game tonight. Been a fan of Mad men for 10 years now. One of my absolute favourite actors."

One Twitter user humorously referenced the half-time prize draw, commenting that the Bridesmaids actor was "checking out the Paradise Windfall numbers" when he was pictured possibly looking up at the screen. 


Another said: "Big Don Draper from Mad Men at the game, go on Jon Hamm."

The American actor has been pictured out and about in Glasgow, stopping by popular restaurant Buck's Bar and posing for pictures with staff.

He was also seen in the city's Botanic Gardens.
