Demi Lovato has spoken out for the first time about why she unfollowed Selena Gomez on Twitter, insisting the pair have ''changed'' and ''grown apart''.
Demi Lovato admits she has ''grown apart'' from Selena Gomez.
The 'Heart Attack' hitmaker and the 22-year-old star were rumoured to have fallen out after Demi unfollowed her on Twitter last month, and she has now spoken out about it for the first time insisting the pair have ''changed''.
When asked why she took such action on the social networking site on Bravo's 'Watch What Happens Live', she said: ''I think it's just one of those things where people change and people grow apart.''
The 21-year-old singer also doesn't appear to hold much of a torch for Selena's on/off boyfriend Justin Bieber as she joked she wanted to kill him.
When asked by host Andy Cohen who she would want to sh*g, marry or kill out of Joe Jonas, Simon Cowell or the 'Never Say Never' hitmaker, she quipped: ''I'd kill Bieber. I'd kill Simon. F**k, I'd kill Joe, too!
''No, Joe and I are good friends, so I wouldn't kill him. I'd keep him around.''
When asked again which one of the trio she would have sex with, she replied: ''None.''
Demi sparked speculation she and Selena had fallen out when she unfollowed her on Twitter in July shortly after posting a cryptic angry message.
In a post that was later deleted, she allegedly wrote: ''Swimming away from the bullsh*t bye b*tch (sic)''
