Bianca Gascoigne and Frankie Essex rocks boob against boob in jaw-dropping cleavage battle

The Celebrity Big Brother star Bianca Gascoigne is the current new face of  Sixty6 magazine, so basically last night was her time to really shine.

Having stripped full-frontal for Sixty6 magazine. and became the new face on the cover, 

The CBB star wasted no time getting her kit off for the magazine's front cover, and proceedings were just as racy for the launch night.

The stars were out in force for the bash with the likes of Marnie Simpson, Olivia Buckland and Jess Hayes in attendance.

And with so many stars around, only flashing the flesh will steal the limelight.

Bianca's skintight number seemed painted on as it hugged her smokin' hot bod.

Covered in embellishment, the dazzling frock almost eclipsed the 30-year-old's mesmerising cleavage.

And deeply plunging at the front, the dress showcased Bianca's jaw-dropping bustline.

But Bianca had some competition, as there was another blonde bombshell vying to steal her thunder.

Frankie Essex rocked up to the glitzy bash, displaying her killer curves in a flesh-flashing LBD.

Cleavage was obviously the theme for the night as the former TOWIE star paraded her perky chest in an equally low-cut mini.

Cinching in her teeny waist with a chunky belt, Frankie highlighted her incredible frame.

While the reality babe polished off her mesh-merising look with nude peep-toes which elongated her shapely legs.
