Adam Levine Ate Cake Alone on His Birthday & Loved It!

Adam Levine shows off his buff, tattooed biceps while touching down at the airport with his Maroon 5 bandmates on Sunday (March 20) in Rio de Janeiro, Brazil.

The 37-year-old singer and the group headed to their hotel where they grabbed some drinks by the pool.

Adam recently celebrated his birthday and shared a photo on Instagram.

“For my birthday yesterday I sat in bed all day with the shades drawn eating this cake completely alone,” Adam wrote. “It might have been the best birthday I’ve ever had. I took time to reflect on so much and had a moment to genuinely appreciate the life that I have and the incredible people I have in it. I highly recommend taking at least one birthday in your life and keeping it to yourself. It f-ckin RULED. And that cake was GOOD.”
