Gisele leaves diners guessing

Gisele Bundchen hasn't confirmed that she's expecting her second child, but spies were on baby-bump watch when she dined in lower Manhattan last week, the New York Post reported Monday.

The wife of New England Patriots quarterback Tom Brady sat with a group of seven, mostly women, and drank only water throughout her meal at La Esquina on Thursday night.

The Brazilian supermodel, 31, wore pants and a tan blazer, but spies believe a small baby bump was visible.

"She looked like she wasn't ready to flaunt the bump and may be trying to cover up," a diner told the newspaper.

The pregnancy rumors were sparked earlier this month when a source told Us Weekly that another member of the Brady-Bundchen clan was on the way.

"Yes, she is pregnant ... they are really happy!" the source told the gossip magazine.

The pair, who married in February 2009, are parents to son Benjamin, aged two.

Brady, 34, also has a four-year-old son, John, from a previous relationship with actress Bridget Moynahan. They dated from 2004 to late 2006.
