Beyonce Baby Bump Picture Fuels Pregnancy Rumors (PHOTO)

Beyonce Knowles and Shawn "Jay-Z" Carter were spotted dining at a restaurant in uptown Manhattan on Sunday and the singer's appearance fueled speculation that the pair may be expecting their second child.

The Hollywood couple casually strolled through the streets of Washington Heights where hoards of fans were able to take cell phone pictures of the pair, and some of the photos revealed what some suspect to be a baby bump.

The Grammy award-winning artists dined at LaMarina at around 7 p.m., and their 8-month-old baby Blue Ivy was not present. Beyonce, 31, was dressed in a figure-hugging Roberto Cavalli leopard dress and fans flocked to Twitter, where her alleged baby bump became a hot topic.

"I knew it! That is definitely a baby bump. Wonder why she would wear such a fitted dress though, guess she's not hiding it this time," Bianca White tweeted.

"OMG is it really true. Check out Beyonce's baby bump! Baby no 2? Me thinks so," Stanley tweeted.

"Is Beyonce pregnant again? I saw her pictures from yesterday. And it seems that she has a baby bump.. what do y'all think #beyhive ??" Ma. Blanca Diamante tweeted.

The pregnancy speculation comes five months after it was claimed that the couple, who has been married for four years, began trying to conceive their second child.

"They see no reason to wait. It took them a while to conceive Blue Ivy, so they don't want to waste another second," a source previously told Star Magazine.

"Beyonce and Jay-Z adore being parents, and they're as hands-on as they possibly can be. Beyonce has found a passion other than music, and it's being a mom," the insider added.

Beyonce has been open about her desire to expand her family, and in a previous interview, she said that she is unsure about exactly how many children both she and Jay-Z, 42, want.

"I definitely want to have more [children]! I don't know how many. God knows I don't know yet," Beyonce told E! News.
