Heavily pregnant t.A.T.u. star Julia Volkova has stunned Russian fans by posing in nothing but her underpants for a new Maxim magazine shoot.

The sultry singer and bandmate Lena Katina posed in their lingerie for the spread, which graces the new issue of Russia's Maxim.

Wearing nothing but black panties, Volkova, who is expecting her first child early in 2008, covers her breasts in the provocative photos, while redhead Katina kneels on a bed beside her bandmate, wearing red knickers and a matching bustier.

The Russian pop stars agreed to pose for the saucy shoot to promote their new album Waste Management.

Volkova isn't the only pregnant star currently gracing a top magazine - Christina Aguilera can be seen showing off her baby bump on the cover and inside the new Marie Claire.
