Jennifer Lopez gave her boyfriend Casper Smart, a truck for his birthday.

Lopez' present was a customized white Dodge Ram truck, according to People Magazine today.

She "knew that Casper really wanted a truck, and Casper was very excited about the generous gift," a source told People Magazine.

The couple reportedly celebrated with dinner at Cecconi's in Los Angeles.

Lopez, 42 and Casper (her backup dancer) began dating shortly after the singer split from ex husband Marc Anthony.
