Britney SpearsBritney Spears might have been suffering from (early) morning sickness not after effects of too much partying when she was sick the other night: according to a report in In Touch Weekly the singer is pregnant again.

A source reportedly close to the star told the magazine that despite her frequent partying of late, Britney has been steering clear from the booze. Speaking about the recent $40,000 trip to Las Vegas, the source revealed: “Her dancers were indulging in Malibu rum and pineapple drinks and taking shots of vodka. But Britney drank bottled water.”

“I’ve seen her during the last two pregnancies and she has the same look now.”

“She’s heavier, but that’s not it. It’s the sparkle in her eye. She always gets that sparkle when she’s pregnant, like she’s relaxed and happy.”

Britney gave birth to second son Jayden James in September, just days before eldest son Sean’s first birthday.
