Model Chrissy Teigen has given lusty fans a final glimpse at her curves before she becomes Mrs. John Legend by posing naked for GQ magazine.

The Sports Illustrated Swimsuit Edition stunner, 27, has bared all for the publication's July (13) issue.

In one surefire classic shot, she leans seductively against a wall, her arms crossed over her chest, wearing nothing but a pair of designer heels.

Teigen also used the accompanying interview to reveal her own mum took the recent cellphone shot of the model getting spray-tanned while nude, which caused a controversy online - the saucy snap was banned from Instagram for violating the image-sharing website's user guidelines.

She says, "What no one knows is that my mum took it! My mum frickin' threw me under the bus!"
