Seth Rogen was left cowering with embarrassment on late night TV on Thursday when one of his most red-faced moments on a chat show was played over and over again.

The star told pal Jimmy Kimmel he was still upset over the way sexy star Megan Fox snubbed his advances when the odd couple appeared on the comic's show in 2007 - and the host made a point of digging out the clip.

Rogen explained, "Often the male guest takes it upon themselves to plant a small kiss perhaps on the cheek of the female guest as they come out. I was thinking, 'When in my life will I ever get the chance to kiss this woman? Now's my chance.' So I tried to do it and... she physically stopped me from doing it and basically rejected me on television."

Kimmel then showed the clip of Rogen's rejection over and over, even slowing it down, so viewers could see him pucker up and then look dejected.

Red-faced Rogen said, "That was so much worse than I remember... It's creepy of me, like, I looked weird in that... I'm one step away from the boob grab."
