Starlets make geek chic

Channing Tatum is a man of many gifts. He's People's sexiest man alive, for starters.

But a potential tech support genius? Not so much.

When his wife Jenna Dewan-Tatum needs help with her devices, she bypasses her better half.

Her go-to? "My step-dad Claude! I call him anytime one of my gadgets isn't working and he can always fix it," she told us.

Dewan-Tatum, Emma Roberts, Emmy Rossum and Olivia Munn hit last week's Microsoft holiday party celebrating the brand's new Experience space in Venice. There, she told reporters that she and Channing Skype when they're apart, and are hugely competitive when it comes to gaming.

She told us via email that she herself feels the "most sexy on a tropical vacation relaxing in the sun with my love. Least -- when I'm sick!"
