Helen Flanagan isn't exactly shy when it comes to posting sexy selfies on Instagram, but the actress let someone else do the camera work for her on Monday night.

Yup, as Helen enjoyed a glass of champagne in a bubble bath - with the foam JUST about concealing her modesty - someone snapped a sultry black and white photo.

And, judging from the caption she posted the snap under, Helen was being FILMED in the bath too!

"Normal night being filmed in a bath at 11pm #zombie #lastnight #wierd x"

We wonder what Helen was filming? She's believed to have wrapped for upcoming thriller Mouse And Cat, while new film Bitch, in which she plays the victim of bullying, has been postponed tip 2014.

Through the powers of deduction, then, we're guessing this bath time scene was for The Other Side Of Love. Bubbles and champagne, not to mention a full face of makeup, just scream romantic drama, don't they?

But, then again, that doesn't really explain why she hashtagged the picture with the word "zombie"...
