The t.A.T.u. star Yulia Volkova is a mum again after giving birth to a son.

The elfish All The Things She Said singer welcomed her second child into the world early on Thursday in her native Russia.

In a posting on the t.A.T.u. website, a representative for the singer reports, "The birth went fast and without any difficulties. Both mother and baby feel good."

Volkova, 22, already has a three-year-old daughter.

The pop star stunned Russian fans by posing in nothing but her knickers for a new Maxim magazine shoot earlier this month.

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