Jessica Simpson sparks pregnancy rumors after being spotted with suspicious bump during her latest outing in Palm Springs, California. The "I Wanna Love You Forever" singer attended a friend's wedding over the weekend.

In some photos obtained by Radar Online, Jessica was seen with larger belly as she greeted pals at hairstylist Christine Symond's nuptials on Saturday, May 13. The "With You" hitmaker wore a cleavage-baring floral print long dress.

Though Jessica normally loves to drink cocktails, she reportedly shunned alcohol at the event. In one picture, she even rubbed her stomach while chatting with husband Eric Johnson and friends.

"She certainly looks at least three months along," says New York City internist Dr. Stuart Fischer, who has not treated Jessica.

According to sources, Eric has been eager for a third baby. "Eric wants another child," explains an insider.

Rumor has it, Jessica's pregnancy was an attempt to save her marriage to Eric. The source adds, "Eric had read her the riot act about her drinking and has threatened to leave her if she didn't quit!"

Jessica is already a mother to daughter Maxwell Drew, 5, and son Ace Knute, 3.
