Double date! Justin Timberlake and Jessica Biel joined Amy Adams and fiance Darren LeGallo for a fun night out on Thursday, Feb. 7, in L.A.

The "Suit & Tie" singer, 32, reunited with his Trouble With the Curve co-star, 38, at Trigg Ison Fine Art gallery, where they co-hosted an exhibition of LeGallo's paintings called "Nothing You Don't Know." Timberlake -- clad in a leather jacket, white button-up, and black hat -- brought as his date his wife of three months, 30, who looked radiant in periwinkle cropped pants, a loose-fitting blouse, and a crisp blazer. 

Adams, meanwhile, supported her artist love in black skinny pants, a white blouse, a black jacket, and blue heels. She and LeGallo, whom she met in an acting class in 2001, have been engaged since April 2008. They have one child together, daughter Aviana Olea, 2.

The outing comes in the middle of a big couple of weeks for Timberlake, who performed a successful two-hour concert at DirecTV's Super Bowl party on Feb. 2 and is set to rock the Grammys stage on Sunday, Feb. 10. Earlier this week, he released the cover art and track list for his upcoming album, The 20/20 Experience, out March 19. 

"Back in June of last year, I quietly started working on what is now my next journey with that thing I love called music," he wrote in an open letter on his website. "The inspiration for this really came out of the blue and to be honest, I didn't expect anything out of it. I just went into the studio and started playing around with some sounds and songs. It was probably the best time I've had in my career."
