Demi Moore has formed a close bond with Demi Lovato.

The 51-year-old actress reportedly met the 22-year-old singer through a mutual friend at a yoga class recently and instantly became pals.

A source told In Touch Weekly: ''They have a lot in common and have gotten super close over the last few months - they even call each other 'DM' or 'DL.'''

The 'LOL' star sees a lot of herself in the 'Neon Lights' hitmaker, as they have both struggled with eating disorders and sought treatment in rehab in the past.

The insider added: ''Demi [Moore] sees a lot of herself in Demi [Lovato]. They're both super into being sober. They do things together, like hike, meditate and talk about boys. They're all about living in the moment.''

Their new friendship is likely to be awkward for Lovato's boyfriend Wilmer Valderrama, 34, who is close friends with Moore's ex-husband Ashton Kutcher, as the duo starred together in 'That 70s Show' in the past, alongside Ashton's now fiancé Mila Kunis.

The couple started dating in 2012 following Ashton and Demi's split and welcomed their daughter, Wyatt, into the world last month.
