Demi Lovato, Naya Rivera Harmonize On 'Glee' Duet

Singers put a harmonic spin on the Beatles' classic 1969 track 'Here Comes the Sun.'

Before Demi Lovato and Naya Rivera play love interests on "Glee," fans are getting to hear what they sound like together on their duet of the Beatles classic "Here Comes the Sun."

Their version, which hit the Internet this week, has the two ladies singing in perfect harmony over a plucky guitar. Written by George Harrison, the track first was included on the Beatles' 1969 album, Abbey Road.

"[Naya Rivera and I] had an awesome time working together," Lovato told MTV News earlier this month. "She's such a badass; I love her. And I've been friends with a lot of the people from the cast beforehand, so I feel right at home."
