Demi Lovato's new romance has received Sam Smith's seal of approval.

The 27-year-old pop star is dating actor Max Ehrich, and Demi has revealed that her showbiz pal is already a fan of her new boyfriend.

Appearing on 'Capital Breakfast with Roman Kemp', Sian Welby asked: ''Demi, you were saying about, you and Sam becoming good friends and I hear that they met your boyfriend and gave him the seal of approval, is that right?''

The singer - who collaborates with Sam on the track 'I'm Ready' - confirmed she'd introduced Sam to her boyfriend, saying she wouldn't introduce ''just anybody'' to the pop star.

She said: ''You know, anybody who meets Sam would be someone that would be very important to me - I wouldn't just, like, introduce just anybody to Sam.''

But Demi - who has previously dated the likes of Joe Jonas and Wilmer Valderrama - has learned to be more coy when it comes to discussing her relationships.

She explained: ''I kind of learned my lesson a little bit with talking about relationships. I would love to gush and explain more, but I just think it's best to keep things to myself.''

Meanwhile, Demi also revealed what she's been doing to pass the time during lockdown, admitting she's developed a passion for playing Uno online.

The music star said she's been using the moniker of Rosemary to protect her identity.

Speaking about her new hobby, she explained: ''I play Uno with random people online.

''I'm under the name Rosemary or something.

''Which I don't know why, it just gave me that name, so I was like sure I'll take it, whatever.

''So now I play with random people on the internet all the time and I'm pretty good.''
