Кристина агилера

Christina Applegate has appeared in a spoof advert for a pre-natal pole dancing DVD while heavily pregnant.

The 39-year-old actress and comedienne - who is due to give birth to her first child in January - stars in the video on comedy website Funnyordie.com as teacher Roxie Fedaro, wearing tiny black hotpants, ripped fishnet tights, and a cropped vest revealing her pregnant belly as she writhes around a pole to raunchy music including Christina Aguilera's Dirrty.

Christina seductively purrs into the camera: "I can't see my lady parts any more but I can still show you how I work them."

Her alter ego Roxie tells viewers: "Many pregnant women experience these things called hormones because you're like a total fat a**. You don't feel sexy any more.

"That's why you need something I like to call 'seducidence'. That's seductive confidence, put together.
