While husband Jordan Bratman hailed a cab outside NYC’s SoHo Grand Hotel on Sept. 2, Christina Aguilera, 27, opted for a limo.
She was hardly a diva the previous night, signing photos of herself for fans. "Her baby Max kept trying to grab the photos," an onlooker tells OK!.
The new mom stirred up old rivalries when it was announced that both she and Britney Spears would be at this year’s VMA Awards. Britney opened the show, and Christina later performed–the first time since giving birth to her son Max, 8 months.
"I’m very excited," she said. "This will be his first time watching me perform on television, but only for a little while because he’s not allowed to watch television yet."
