So you would think that Sam Faiers and Amy Childs would be wearing the skimpiest bikinis during the TOWIE gang's week-long Marbella sojourn.
But the buxom girls surprised their fans by covering up today - while their lesser-known co-stars paraded their bikinis bodies on the beach
Here come the girls: Jessica Wright, Lydia Bright and Lucy Mecklenburgh of The Only Way Is Essex take a stroll on the beach in their beachwear in Marbella
Sam, 20, played peekaboo in a sheer black and white kaftan which gave a glimpse of her black bikini and model figure.
Sam was pictured strolling through the shops earlier in the day with her boyfriend Joey Essex and their friends, and she posed for some holiday snaps sitting atop a gold lion.

Amy also kept her surgically-enhanced assets covered up in a white vest top.
The beautician was certainly in holiday mode as she wondered around half-dressed in her hot pink bikini bottoms and platform flip-flops.
Meanwhile, Sam and Amy's co-stars Jessica, Lydia and Lucy made the most of the cameras as they strolled along the shoreline in their skimpy swimwear.

Lydia Bright wore a tight-fitting white mini dress so short it showed off her white bikini bellow, which she wore with an oversize colourful necklace.
The Only Way Is Essex gang were joined today by Sugar Hut nightclub owner Kirk Norcross and his girlfriend Lauren Pope.
