London, May 03 : Miley Cyrus has reportedly grown increasingly close to young British actor Gregg Sulkin - something that may break the heart of the actress' US model beau Justin Gaston.

The multi-millionaire Hannah Montana star and Gregg met at a party thrown by Disney studios earlier this year.

After that, they have kept in touch and met up for their first dinner date last week while she was in London to promote her new Hannah Montana movie.

According to pals, the pair are ready to come clean about their romance.

"Miley thinks Gregg is just awesome. She's taking it one step at a time but they both would love to make a proper go of it," the Daily Star quoted a pal as saying.

"They are still really very young. It's all quite sweet, really.

"The thing with Justin wasn't that serious - but with Gregg it could be for keeps," the pal added.

Dad Billy Ray Cyrus is also a big fan of Gregg and thinks he is `good for Miley'. (ANI)
