Finally after two years of marriage, Adam Levine and Behati Prinsloo are expecting a baby, and the Maroon 5 vocalist isn't afraid to show off his excitement.

"I'm gonna be a f**king dad!" th ecoach of "The Voice" told Entertainment Tonight, after being congratulated by his showbiz colleagues and fans for his wife's first pregnancy. "I'm so excited!"

The 37-year-old singer was on the set of "The Voice" with rock legend Sammy Haggar whom the former requested to help mentor his team during the Battle Rounds

Hagar, who has four children, was happy with the news of Levine's fatherhood, as he extended his heartfelt congratulations to the singer-songwriter.

Adam Levine and Behati Prinsloo's baby is set to arrive in September, a celebration of their two years of marriage.

"It'll be the greatest day of your life, the day that baby is born," Hagar told a beaming Levine, who replied with an ecstatic "oh, hell yeah."

The Maroon 5 front man may be in Cloud 9 right now as an expectant dad, but that doesn't mean he's gone soft as a mentor.

In fact, Levine is gearing up for the competition in The Voice season 11, as he goes up against longtime friend and rival Blake Shelton, and the show's newcomers Miley Cyrus and Alicia Keys.

"Alicia's is the strongest team, mine is probably a not-so-distant second," he declared.

"And then third and fourth, I'm not gonna go down that road and make more enemies," Levine added.

In the meantime, Prinsloo, like her husband, has become the epitome of an expectant mom, as she frequently shows off her baby bump on social media.

She has also been bonding with her fellow pregnant model Candace Swanepoel.

In one of her recent Instagram posts, the Victoria's Secret model showcased her baby bump (and her feet) as she took a dip in the bathtub.

"Still can't believe me and my African sis are expecting at the same time...So many good times together and so many more to come. LOVE YOU," Behati Prinsloo said in the photo's caption, which definitely made Adam Levine smile.
