Justin Timberlake is back with the new single "Suit and Tie" ... and we're obsessed!

The 30-year-old newly married singer is putting his acting career on hold in the hopes of climbing the music charts once again. This is JT's first single since 2006.

Jay-Z is featured on the infectious track. The single will be included on Timberlake's upcoming album The 20/20 Experience due out later this year.

Wonder if JT's wife Jessica Biel is lovin' his new sound, too? We'll guess the answer is yes!
