Russian Prime Minister Vladimir Putin's alleged mistress is planning to release Barbie-style doll of herself in a bid to inspire young children to follow in her sporting footsteps, a media report said.

Alina Kabayeva, the 27-year-old former Olympic gymnast, has already applied to trademark the new doll -- 'The Alina doll' -- with the Russian patent office and is awaiting a reply, The Daily Telegraph reported.
