Kelly Osbourne has claimed that the reason behind Lady Gaga's dramatic weight gain is because she is pregnant.
Recent pictures of the 'Poker Face' singer have emerged looking noticeably larger to her usual svelte frame.
Talking to Alan Carr on tomorrow night's episode of 'Chatty Man', Kelly proposed her theory.

She told Alan: "I think she is pregnant because she has been covering up this part of her body recently and I have been noticing that a lot."
Kelly also pointed out that as well covering up her body, the singer's change in hair color was also a tell tale sign of pregnancy.
She explained: "And her style has changed and you can't bleach your hair blonde when you are pregnant."
And what about shaving the back of her head Kelly, is that also a sign?
However, it seems that Kelly is not alone in believing that a baby Gaga could be on the way.
Rumors have been running rife after the star was spotted throwing up backstage at a gig in Romania.
The singer caused controversy earlier this week after she smoked a marijuana cigarette on stage while performing in Amsterdam.
