Alec Baldwin and the Jonas Brothers have signed up to headline the Valentine's Day installment of the U.S. sketch comedy series "Saturday Night Live."

The Feb. 14 show will mark Baldwin's 14th appearance as "SNL" host. The Jonas Brothers are set to be the evening's musical guest, NBC said.

The network added that "He's Just Not That Into You" co-star Bradley Cooper will be the host of this Saturday's show, which will feature the New York-based soul rock band TV On The Radio as the night's musical entertainment.
