Lighting up: Miley Cyrus smokes a cigarette while smoking a cigarette and holding her new puppy Floyd in Orchard Lake, Michigan yesterday
She may be famous for being a Disney star, but Miley Cyrus is starting to look markedly different from her Hannah Montana days.
The former Disney star sported a slinky grey bikini which showed off her slender figure and growing number of tattoos as she spent the day with boyfriend Liam Hemsworth at a Michigan lake yesterday.
And it seems the actress and singer has also developed a nasty habit as she was spotted lighting up several cigarettes while soaking up the sunshine.

The star was clearly having a great time as she carried her brand new puppy Floyd with her on the jetty, and clung on to him when she took a dip in the water, at Orchard Lake.
The pooch was by the singer's side all day, and she later changed into a white vest top and red patterned skirt to take him for a walk.
Later, the star took a ride on a jet ski with her Australian boyfriend, Liam, 21, who has just been filming his new role in the hotly anticipated film adaptation of The Hunger Games

It's clear that the Hannah Montana star's relationship with the actor - her co-star in film The Last Song - is firmly back on after the pair split briefly last year.
They were joined by Miley's friend, former star of reality show The City, Erin Lucas.
'Lake day with @erin_lucas and our bfs :),' Miley wrote on her Twitter page yesterday. 'We already put them do a coffee run but it's taking WAY tooo long!'

Her new smoking habit comes in contrast to comments she made in her 2009 autobiography Miles To Go, according to the New York Post.
'I would never smoke,' she wrote. 'I always say that for me, smoking would be like smashing my guitar and expecting it to play.
'I'd never do that to my voice, not to mention the rest of my body,' she added.
