Adam Levine rang in his 38th birthday on Saturday, and wife Behati Prinsloo wasted no time in showering him with love on Instagram. The Victoria's Secret model commemorated the special occasion with a silly black and white photo of the pair, writing, "THE LOVE OF MY LIFE. Happy birthday 💋." She then followed up her snap with a shot of Adam wearing a pink beanie in a bathroom and captioned it, "BIRTHDAY BABE." During Adam's recent Hollywood Walk of Fame ceremony, the Maroon 5 frontman gushed about his family in his speech, saying, "I have a daughter. I have the most beautiful wife in the entire world. I am one of the luckiest people who's ever lived and it has nothing to do with me." Could these two be any cuter?
