Britney Spears has again ignited pregnancy rumours after she was spotted leaving a medical centre with her father Jamie in LA yesterday.

The troubled star has sported a rounded stomach in recent times, and her latest outing has only served to further fuel whispers.

Rumours: speculation the star is expecting her third child continue to swirl

News of Ghalib's apparent bragging was first reported in Us Weekly, and another U.S. publication, Life & Style, has also speculated the star is with child.

But the paparazzo's relationship with Britney appears to already be in tatters after he was reportedly seen getting cosy with LA waitress Amanda Pagel this week.

Britney, who has only just regained visitation rights to her children Sean Preston, two, and Jayden James, 17 months, was spotted holding a pregnancy test in a chemist's shop in January.

If the rumours prove true, it will no doubt be a huge blow for Britney's parents who are desperate for their daughter to pull her life together.

While the former pop princess has been offered support by a list of stars, most recently Heidi Klum, she is not getting any sympathy from Mr Nasty Simon Cowell.

The American Idol judge said in a recent interview that Britney has only herself to blame for her troubles.

Cowell said: "I think she's manipulated the whole thing, like waving a pregnancy test at the cameras."

"I've heard she won't leave the house until there are enough photographers there."

Weighty matters: the star looked bloated during the outing

He was also unimpressed by Spears' latest musical efforts, saying: "I hated Britney's last album."

"That song 'Gimme More' sounded like a ringtone - it reminded me of that awful 'Crazy Frog' song. Utter rubbish.

"She could well have had her last No.1. And certainly her last meaningful one."
