Snooki and her fiance Jionni LaValle made an appearance at Citi Field in New York City on Monday to meet the New York Mets, one of the "Jersey Shore" star's favorite teams. But the guidette wasn't met entirely with open arms.

The reality star swung a bat on the field, showed off her baby bump, and posed for photos in the dugout. But when her face appeared on the jumbo board, she was greeted by a booing crowd.

However, she took the negative reaction in stride, tweeting, "Lol I love it" @spielster: Love that a whole stadium just booed @snooki. @Citifield."

She also replied to another poste...

"The fact that I can reproduce is very scary," says Nicole "Snooki" Polizzi in the trailer for her new MTV show "Snooki & Jwoww." She wasn't the only one scared by the revelation - MTV execs were in a tizzy when they found out the "Jersey Shore" star was expecting.

Rather than shutting down production, the network decided to capitalize on the new development. And judging from the show's new trailer, they made the right decision.

Reality TV star Nicole 'Snooki' Polizzi is engaged and expecting a baby.

The Jersey Shore star's boyfriend Jionni LaValle proposed last month and now GossipCop.com reports the pint-sized 24 year old is also pregnant.

The news should come as no surprise to fans - she recently told People.com, "I know he's (LaValle) the one so I know the ring's gonna come soon."

Snooki is currently in the middle of filming her own spin-off reality series with best friend Jennifer 'JWoww' Farley in Jersey City...
