Adam Levine gave his full support to his wife on her new fashion line.

On Tuesday, the Maroon 5 rocker posted a photo of his spouse, Behati Prinsloo, in a stunning shot with her white shirt and striking expression. As she advertises the line for Juicy Couture, Levine called Prinsloo his "bad a-s wife."

He added that everyone should get this brand because it's "super awesome."

Levine celebrated his 37th birthday earlier this week although he spent part of the time by himself with one giant cake. But rather than feeling depressed that no one was around, the singer used this time to count his blessings and be thankful for what he has going on for him.

Not to mention, plenty of more cake for him.

After being married for more than a year, Levine and Prinsloo are reportedly expecting their first child who will likely be born sometime this fall. And according to Hollywood Life, Levine's friend and Voice co-star Blake Shelton (and his girlfriend Gwen Stefani) might be throwing the couple a baby shower.

"Blake said he wants to throw a baby shower with Gwen," the source revealed. "He was half-joking, but he seems like he wants to be involved and be there for Adam, all jokes aside."
