Adam Levine is celebrating his wife Behati Prinsloo’s birthday with cake — her cake.

The Maroon 5 frontman took to his Instagram Story Tuesday to pay tribute to the model on her 35th year of life by sharing a close-up shot of her backside.

“happy birthday baby ????,” Levine wrote alongside the snap, which showed Prinsloo wearing loose-fitting jeans atop white-and-black panties, which she accessorized with a gold belly chain.

The former Victoria’s Secret Angel was seen carrying the couple’s new baby, who sported nothing but a diaper, though their heads and faces were not visible.

The musician, 44, and Prinsloo reportedly welcomed their third bundle of joy in January but did not announce the infant’s arrival until March.

They have yet to reveal the name or sex of their family’s new addition and famously keep their kids’ faces off social media. (They also share daughters Dusty Rose, 6, and Gio Grace, 5.)

News that the South Africa native was pregnant with baby No. 3 broke in September 2022 — the same month her husband found himself in some hot water for sending flirty Instagram messages to several women, including models, influencers and even his former yoga instructor.

The first woman to come forward with allegations of an affair — which she claimed included a “physical” relationship — was model Sumner Stroh, who posted one particularly disturbing DM from the singer that read, “Ok, serious question. I’m having another baby and if it’s [a] boy I really wanna name it Sumner. You ok with that? DEAD serious.”

Levine denied cheating on Prinsloo but admitted his behavior “crossed the line.”

“I used poor judgment in speaking with anyone other than my wife in ANY kind of flirtatious manner,” the Grammy winner said in a statement at the time.

“I did not have an affair, nevertheless, I crossed the line during a regrettable period of my life.”

Levine acknowledged that his interactions “in certain instances” became “inappropriate” but insisted, “I have addressed that and taken proactive steps to remedy this with my family.”

Such seems to be the case, as Prinsloo has stood by his side since the scandal made headlines. In the months that have followed, the couple have flaunted plenty of PDA at public events and on social media alike.

The stars began dating in 2012, got engaged in 2013 and said “I do” in 2014.
