Kris Humphries' ex-girlfriend is going under the knife to look like his ex-wife Kim Kardashian.

Myla Sinanaj, who dated the basketball player for a few months following his split from the 'Keeping up With the Kardashians' star in October 2011 after 72 days of marriage, admits she is ''obsessed'' with Kim's body.

She told gossip website TMZ.com that even though she is fed up of being compared to the reality TV star, she wants to look more like her in a bid to carve out a career in Hollywood.

She said: ''I'm obsessed with her body and want mine to be exactly the same.''

She added: ''I know it will launch my career.''

The aspiring star is set to undergo $30,000 worth of procedures next month, including liposuction, lip injections and breast augmentation.

Despite idolising Kim's figure, Myla previously accused the brunette beauty of getting private investigators to spy on her in July 2012 after she was subpoenaed by Kim's legal team to talk about her relationship with Kris as part of their divorce proceedings.

Myla also slammed Kim on Twitter and urged her to leave her alone and stop ''dragging'' her into the former couple's ''drama''.

After a bitter battle, Kris and Kim reached a divorce settlement in May, just one month before she gave birth to her first child, North West, with her boyfriend Kanye West.
