It's been a while since we last saw Sophie Monk, but the Aussie model is still rocking her sweatpants -- and that cartoonish pout. Ahh, good to know that some things never change!

After breaking off her engagement to Jimmy Esebag (remember, the dude who was 20 years older than her?) Sophie has been maintaining a relatively low profile and steering clear of the gym the nightclubs. Sigh, what happened to the blonde hottie who used to date Benji Madden?

Sophie Monk said Sunday that she was not only "newly single" ... but ready to "turn Samantha Ronson!"

Someone call Lindsay Lohan!

Monk announced her engagement to businessman Jimmy Esebag, who's 20 years her senior, back in January.

But now the Aussie beauty has called it quits. While taping an episode of Chelsea Lately from her native Australia Sophie revealed the split.

Newly engaged Australian model/actress Sophie Monk has admitted that she regrets getting plastic surgery, along with the image that goes along with it. "I’m so sick of people saying that just because of my lips, I’ve had surgery everywhere," she told Australia's Who magazine.

Monk says it all started when she had collagen injected into her lips following the botched removal of a cyst. "Half of my lip was removed with the cyst, and I was advised to get filler in my top lip to help balance it out. I should have said no to the filler in the first place but I trusted the doctor." No word on who the doctor was, but many speculate it was her ex-boyfriend, plastic surgeon Dr. John Diaz, whom she later broke up with when she caught him in bed with another woman.

Monk also revealed that she's struggled with her eating habits over the years. "The stress of this business tends to come out through my body. Either I eat too much or I eat nothing. I need to be more responsible for my body," she said.

So Monk seems to claim that the only thing she's had done is her mouth, but after looking at these before and after shots, is it possible there may have been a few other procedures as well?

Yesterday we spotted Sophie Monk out and about in Hollywood, and the newly engaged Aussie starlet was snapped with some bling on her ring finger, but we're not sure if this is from her fiance Jimmy Esebag. Don't you think a businessman who is 20 years her senior would buy a 4 or 5 carat diamond sparkler for his lady? Or maybe their love goes beyond material things?

31-year-old Sophie Monk announced that she had gotten secretly engaged to American businessman Jimmy Esebag, who's 20 years older!

Monk made the announcement on the Australian radio station 2Day FM's breakfast show, which she's currently co-hosting from here in LA.

Monk said "I got engaged, and I kept it quiet so no-one's heard much about him." Of her new fiance, she gushed, "He's a 'keeper'. It feels right. I think you know when you know."

So just who IS Esebag? He's the chairman of the board of America's Licensing Holding Group, which owns the rights to the Playboy brand.

But hopefully, Esebag is no playboy himself. Monk went through a very painful breakup with her last beau, plastic surgeon Jason Diaz, last year, after allegedly catching him in bed with another woman.

Monk was previously engaged to Good Charlotte's Benji Madden.

First of all, check out those long, toned legs! Katie Holmes has got some competition...

Model/actress/singer Sophie Monk showed off her worked out bod in Beverly Hills on Wednesday morning; the beautiful babe was spotted carrying four coffees over to her friend's house. Hot or not?

Sucks to be her!

Yesterday X17 photogs snapped Sophie Monk minutes after she was pulled over for texting and driving, and the Aussie supermodel didn't seem upset at all. Heck, she didn't even seem annoyed about the gigantic gash on the right front bumper of her shiny black Lexus. So how did that happen? Click the video above to find out...

I know the dreary Los Angeles weather is cramping everyone's style this week (hey, it's better than 110-plus degree heat!), but Sophie Monk looks like she fell into a sea of bad outfits and makeup since we saw her last. Not sure what she's working on these days in terms of modeling gigs, but this is definitely NOT her best look...
