Recent pictures of the 'Poker Face' singer have emerged looking noticeably larger to her usual svelte frame.

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.
