J. Lo Buys New Truck for Casper Smart's Birthday (VIDEO | 9 PICS)

No doubt about it: 25 is a big birthday. And when you're Jennifer Lopez's boyfriend, prepare for a serious celebration.

According to People magazine, the superstar bought her beau, Casper Smart, a customized white Dodge Ram pick-up truck. A source told the magazine, "Jennifer had planned a fun day to celebrate Casper's birthday, adding, she "knew that Casper really wanted a truck, and Casper was very excited about the generous gift."

J. Lo tweeted her excitement for her BF's big day. "Beau has a birthday we're so glad we hope its the happiest Birthday Beau ever has!" #singingtweet. HAPPY BIRTHDAY BEAR!!!"

With a gift like that, it's pretty much guaranteed to be his best birthday yet. Smart immediately made use of the practical present by driving himself and Lopez to his birthday dinner at an Italian restaurant in West Hollywood, where they were joined by friends. A photo of the two in Casper's new ride shows the couple all smiles.

Lopez has plenty to smile about. She debuted her new, racy video "Dance Again," which features Pitbull and some sexy dancing with Smart involving glitter and blindfolds.

Comments on the Web were mixed about J. Lo's generosity. While one fan worried, "Honestly, doesn't she want a man who doesn't depend on her money. She's buying him." "It was very nice for her to buy the current beau a truck." Another applauded, "good for her for doing what she wants." Another agreed, "She is HAPPY and thats what matters."

The "American Idol" judge was first spotted with the back-up dancer in the fall of last year, after her split with husband Marc anthony.
