She's come a long way since "Jenny from the Block!"

Jennifer Lopez looked ravishing in a sexy red dress and suede Christian Louboutin Bis Un Bout pumps, as she arrived to her surprise 43rd birthday party on beau Casper Smart's arm aboard a private yacht in NYC, on Tuesday evening.

The day before her lavish party, Smart was seen picking out items at a racy adult's only shop in The Big Apple, so there's no doubt the former American Idol judge received a pleasurable surprise this year!

After the festivities, La Lopez indulged in a sweet birthday treat, sharing via Twitter: "Mr.Softee vanilla cone w/sprinkles on my birthday!! #itsaNewYorkthing #happygirl. Somebody loves me...:)"

Happy birthday J. Lo!
