Cyrus 'to get Justin Gaston tattoo'

Miley Cyrus plans to get a tattoo of boyfriend Justin Gaston's initials, say reports.

The 16-year-old popstar has asked her parents if she can get a heart with the letters JG inside, according to MTV.

"She's trying to play her mum, Tish, against her dad to get one of them to agree to the tattoo," commented a source.

Cyrus has apparently had similar temporary pieces of body art, but now wants to make her relationship official with permanent ink.

She and the 20-year-old underwear model have been romantically linked since October 2008.
