Bette Midler has blasted singers including Britney Spears and Christina Aguilera for not showing any "emotion" in their performances.

The musical legend - who is currently in Las Vegas completing her 'Showgirl Must Go On' residency - argues young stars need to put more depth into their shows.

The 27-year-old beauty - who appeared in an erotic sex tape with then-boyfriend Ray J in 2007 - recently revealed she wants to get her ample butt insured.

Kardashian said: "I have not insured it yet, but I think I should look into that. I have no idea where this all attention came from. I have always dressed the same - it's nothing new.

Christina Aguilera's feet increased by two sizes when she was pregnant. The 27-year-old singer - who gave birth to Max Liron, her first child with husband Jordan Bratman, in January - admits she was stunned by the amount her petite feet ballooned in size.

She said: "My stomach was really where I carried my weight. Toward the end of my pregnancy, I felt really big - I gained about 40lbs, which is a lot for my size. My hips also changed significantly. And my feet grew from a size five-and-a-half to a size seven in flats!"

Britney Spears' Mickey Mouse Club T-Shirt she owned is up for auction. A memorabilia site would be auctioning a piece of the pop princess' Mouseketeer past starting on July 21.

GottaHaveIt.com will be having a special online auction entitled "The Rock & Roll Pop Art Auction" from July 21 to August 6, which will feature original handwritten lyrics and letters and other rare items by the music industry's greatest living and dead legends.

Christina Aguilera hires babysitters when she wants to have sex with husband Jordan Bratman.

The 'Dirrty' singer - who gave birth to the couple's first child, Max, in January - insists their baby is their priority but the couple also need to spend time alone.

Christina Aguilera has defended her late night partying. The 'Dirrty' singer - who gave birth to son Max Liron in January - says she is entitled to go out and enjoy herself with husband Jordan Bratman despite being a mother.

She said: "I spend all day with my son and once in a while if I want to go out and have a mommy-daddy night with my husband, I am more than allowed to do that."
