London, Sep 20  :  Singer Kelly Osbourne believes singer Lady Gaga is pregnant.

The 27-year-old has alleged Gaga is covering herself up these days the way only pregnant women do, reports thesun.co.uk.

"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," Osbourne said during Alan Carr'c chat show.

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

Gaga is currently dating actor Taylor Kinney.
