Miley CyrusMiley Cyrus has added her voice to the choir of celebrities suggesting that Britney Spears needs help as her behaviour spirals further and further out of control.

The Hannah Montana star told Extra this week: “I think it’s so crazy and I think that [Britney] needs help.”

“If I didn’t have [my family], I’d probably be in the same position. You just got to know who your true friends are, and I think for me, is my mom.”

“If you have sisters, I mean any girls that are in your family, that can understand and relate to you, I think is the best.”

Britney is said to be still somewhat estranged from her mum after she felt Lynne pushed her into rehab last year and hasn’t seen little sister Jamie Lynn Spears since the 16 year old announced her pregnancy last month.
