Blink and you'll miss her! Imogen Thomas makes a cameo in Shameless wearing her underwear (but she doesn't have any lines!)
The 29-year-old made an appearance in the hit Channel 4 programme, Shameless, but it wasn't exactly a BAFTA-winning performance.
Viewers watching the episode may have missed Imogen's cameo, had they popped to the toilet or blinked while looking at the screen.

Memorable performance: Imogen Thomas made her cameo in Shameless on Wednesday night
The Welsh star was on the screen for no more than 30 seconds, but she certainly made herself known.
She is first seen chatting away to two women across the road as Billy Tutton, played by Michael Taylor, sits with two friends watching her.
As Imogen gossips with the ladies, wearing a short floral dress, tights and heels, Billy is seen telling his friends 'to be quiet' as he is trying to 'concentrate.'
Different looks: The brunette is first seen wearing a floral dress but her clothes are then whipped off after Bully Tutton uses his mind powers to do so
The two men begin laughing, but soon go silent as Imogen begins walking towards them.
As the brunette crosses the road, her clothes are completely whipped off from her body which leaves her standing there in black and pink sexy underwear completed with stockings and suspenders.
As she gasps and clutches her chest, the Welsh star is seen running away as Billy shouts: 'I f***ing did it!'

Imogen was clearly very excited about her appearance on the award-winning show and kept reminding her followers that the episode was on.
'Morning!!! I make a brief appearance on shameless tonight @ 10pm!! Very fun :-) tune in....:-) xxx' she tweeted, before adding: 'Tune into shameless tonight! On C4 @ 10pm :-) xxx'
The former Big Brother enjoyed a night out at the Total Hair Experts launch in London, but made sure she was back in time to watch the show.
