Johnny Depp has reportedly split from his girlfriend.

The 56-year-old actor - who was previously married to Amber Heard and Lori Anne Allison and has children Lily-Rose, 20, and Jack, 17, with ex-partner Vanessa Paradis - began romancing Polina Glen earlier this year but the dancer has ended their relationship and returned to her native Russia after becoming overwhelmed by the attention their relationship received.

A source told the Mail on Sunday newspaper: "Polina hated the attention the relationship was bringing her and found it scary.

She's now keeping her head down in Russia and told Johnny plans to get married were madness."

And the 24-year-old beauty felt the 'Pirates of the Caribbean' star was too "distracted" by his ongoing legal battle with ex-wife Amber - who he is suing for defamation over her allegations of domestic abuse - to be fully committed to a relationship.

The insider added: "Despite sneers that Polina was only with Johnny for his fame, she kept her head down while living with him, going to her dance choreography job and then back to his house.

"His level of celebrity and his ongoing battle with Amber grew too much for her.

"Johnny has been distracted by his feud with Amber and she didn't think the time was right for them to commit to anything."

Polina is thought to have spent the spring and part of the summer moving between Johnny's house in California and her homeland but has now returned to Russia "for the foreseeable future."

It was previously claimed the dancer had no idea who the 'Fantastic Beasts: Crimes of Grindelwald' actor was when they first met.

A source said earlier this year: "Polina met Johnny at a party in LA. She gets invited to a lot of stuff and ran into him. She's a dancer and a hot girl.

"She was just chilling at the party and didn't know who he was when he came over to introduce himself. They hit it off.

"He's got legal issues with his ex-wife and then here's this beautiful young Russian dancer, that doesn't want anything and doesn't even know who he is. The Russian girls don't know him. They have no clue about actors and people always look different in person.

"When she found out who he was, she was happy.

"She's really sweet and caring. She's very talented. I'm sure Johnny assists but she's off doing her own thing.

"She is very low-key. She goes to her dance choreography from his place and she comes back. I don't think anyone knows she's living there."
