Well, she kinda had to, you know, given she probably has several spare rooms going a begging. That and - again - it helps that Jesse's got model looks (still going to hell).

The singer "shocked" onlookers at the MTV Video Music Awards in Los Angeles on Sunday by not twerking with a middle-aged man (he looks middle-aged)... she instead turned up with a homeless friend, and now she's gone that extra mile by inviting Jesse to move into her gaf.

A source told the Daily Star: "This is all part of Miley's reinvention. Her mum Tish brought in a new team of advisors to give her a make-over after she lost a lot of support with her extreme antics and sexy performances. Taking him as her date to the VMAs worked really well for her and she wanted to help Jesse in other ways. He's being given top treatment at Miley's home by a team of staff doing his laundry and cooking for him. She now wants to be seen making a difference."

The 21-year-old pop star shot to Jesse's defence on Tuesday night after it was revealed there was a warrant out for his arrest. And you can read all about that here...
