Cellulite hell: Mischa is clearly having issues with cellulite despite her youth as the back of her thighs are very dimpled

Host: Mischa was in Australia on presenting duties at the MTV Awards

The nasty habit is one of the reasons that can be attributed to the premature emergence of her cellulite.

Mischa was staying at the uber-luxurious Qualia Resort on Hamilton Island with her mother Nuala after flying over to attend the MTV Music Awards.

She told an Australian newspaper: "I went jet skiing and scuba diving and saw some beautiful coral.

"I haven't had a vacation in a long time so I just laid out and relaxed - it's just been the two of us with our own pool.

"Real mother-daughter time."

However, there were reports that MTV was disappointed with her "lacklustre" presence. And she was understandably upset.

She said: "That's wild. I was asked to present and do a half-day of press and phoners and I did that.

"I was just quiet because I was chilled.

"I went to quiet dinners in Sydney so I could meet people and experience the city.

"I really like it here."
