Is Lady Gaga Pregnant Or Just 'Fat?' Kelly Osbourne Says She's Expecting

Lady Gaga has undoubtedly gained weight in recent months, which can be seen in photos from her concert in Amsterdam.

The typically slender singer -- real name Stefani Germanotta -- is far from fat, but she currently has more curves to her body than in the past.

Reality TV star Kelly Osbourne said of Lady Gaga’s weight gain: “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.”

Osbourne was referring to Gaga wearing a burka during a London Fashion Week event.

Gaga’s entire body was nearly drowning in the material and the burka, of course, left only slits for her eyes to peer through.

Rumors that Gaga might be pregnant began swirling about a week ago when she was seen throwing up backstage at a concert in Romania, the Daily Mail reported.

If Gaga is pregnant it would probably be a happy surprise for the singer, who has been dating hunky “Vampire Diaries” actor Taylor Kinney since late last year.

On the other hand, some recent events cast doubt on the story.

Osbourne spoke before Gaga smoked marijuana during a gig in Amsterdam. Her theory that Gaga was pregnant was based on the “Born This Way” singer changing her behavior, so it’s unlikely that she would not dye her hair because of being pregnant and then smoke a joint on stage.
