Kelly Osbourne thinks that Lady Gaga is pregnant.

The outspoken Fashion Police star shared her observations on the "Born This Way" singer's noticeable weight gain and claimed Gaga - who is dating Vampire Diaries actor Taylor Kinney - has been hiding her stomach lately.

"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. And her style has changed and you can't bleach your hair blonde when you are pregnant," she said.

However, Kelly's comments came before Lady Gaga praised marijuana as she lit up on stage in Amsterdam.
