Katy Perry's 37th birthday became a memorable occasion with the release of her collaboration with GAP.

The singer performed her own version to the Beatles' 1967 track "All You Need Is Love," for the commercial.

The birthday girl was captured sporting different Gap clothes in the ad.

She ended the footage on a high note while performing in an all-pink sweatsuit.

The "Roar" crooner has dreamed of joining GAP's playlist since she was a teenager.

The iconic singer described the experience as a "bucket list moment."

The streaming of Perry's Beatles cover would also help donate money to charity.

The 37-year-old shared her views about not having a Grammy Award.

Perry revealed the real reason she felt powerful and it wasn't her success.
