That's a little lace-y! Mischa Barton risks a wardrobe malfunction in unusual romper and corset combination  

It's her party and she'll get adventurous if she wants to.

Mischa Barton ensured all eyes were on her in more ways than one in Los Angeles on Wednesday night.

The 30-year-old celebrated her first big job in a while in a rather unexpected look.

Red-y, set, go: Mischa Barton ensured all eyes were on her in more ways than one in Los Angeles on Wednesday night for a celebration of her new show Joyride

Mischa is the new host of Joyride for the Esquire Network, so was the star of the red carpet at the event.

Even if she was not the host, The OC star would have got her fair share of attention in a plunging red romper.

The onesie featured cropped pants and daringly low neckline with an unusual lace-up corset at the front.

Fortunately for Mischa, the corset kept the romper firmly against her body and it was the only thing that stood between the actress and a wardrobe malfunction.

Bending over to fix her shoe, the new host almost bared all but fortunately the romper's material stayed put.

Mischa was joined at the event by her fellow co-host T-Pain, who also wore red.

In the show, the duo joins professional race car driver Brian Vickers and actor Oliver Trevena as they compete against each other to find the best new and vintage cars in a number of different categories.

The six half-hour episodes will include Best Classic Truck, Best British Car, Best 80s Car, Best Car for a First Time Driver, Best Muscle Car of the 1960s and Best Midlife Crisis Car.
