Earlier this week it was revealed that the pair had became parents for the first time when their daughter - Dusty Rose Levine - was born on Wednesday (21 September).
And a proud Adam couldn't resist sharing a seriously sweet snap of his little girl, which he uploaded to Instagram today (24 September).
In the black and white picture, Dusty can be seen peacefully sleeping on her dad's bare tattooed chest and looks tenny tiny as she snuggles into Adam.
Too cute to handle!
The Voice US coach Adam simply captioned the image with "Dust Rose Levine 9/21/16", while Behati uploaded the same photo and added "Words can't describe".
Fans of Maroon 5 were aware that Adam's baby was on the way when the band cancelled upcoming shows due to the expected arrival of Dusty. The 'Moves Like Jagger' singer also uploaded a video to Twitter apologising to fans and promised that the gigs will be rescheduled early next year.
According to sources, the pair are obviously made up with Dusty's arrival, with a report in Us Weekly revealing: "Everything went well and the baby is beautiful. They're a very happy couple and excited to start their family. I can tell you they make very beautiful babies together."
And a second person told E! News: "Adam was in the delivery room holding Behati's hands. They both cried when she was born. Both families are there now. She is beautiful. She looks like Behati."
After seeing this photo of Dusty, we certainly agree that she's gorgeous!
Adam and Behati married in 2014 and first announced their pregnancy news back in March this year.
