Watch Rihanna's Racy NBA Half-Time Show; See Kim Kardashian Do Keg Stand (Links)

While Rihanna continued to shock her fans with a seriously racy but typical routine at the NBA All Star Game on Sunday night, Kim Kardashian along with mom Kris Jenner performed keg stands on 'Kourtney and Kim Take New York'.

First there is Rihanna who is known for exhibiting the shock factor when performing. On Sunday, the NBA All Star game took place at the Staples Center in Los Angeles and at half time, Rihanna along with Drake and Kanye West performed.

Rihanna's performance of major hits 'Umbrella' 'Rude Boy', and 'Only Girl (In the World)' was entertaining but some reports are saying she basically crossed the line when she grabbed her crotch while performing her single 'S&M'.

Rihanna caught flack from the Daily Mail online which said that she 'shocked' the audience which was comprised of celebrities and families out to see a ball game.

Last year in the UK Rihanna performed on the 'X Factor' and 4,500 complaints were lodged to OFCOM (the independent regulator and competition authority for the UK communications industries) regarding her skimpy outfits and raunchy dance routines.

And causing perhaps a bit of controversy was the ever popular Kardashian clan who on 'Kourtney and Kim Take New York' egged Kim and later mom Kris Jenner to perform keg stands.

While it's not really shocking to see a 30-year single gal perform a keg stand (i.e., Kim), the fact that her 55-year-old mother (Kris) held Kim's legs up in the air may have crossed the line in some viewer's minds.

Further fueling the wagging tongues was when Kris herself performed a keg stand.

The Kardashian ladies were celebrating Kim's 30^th birthday and were trying to cheer up Kim who seemed bummed about turning the big 3-0.

Later big sis Khloe said that their mother Kris was "acting like it's her 30^th birthday." At this juncture Kourtney decided to give Kim a "frat party" to help her loosen up. Although Kim was reticent to do the keg stand and admitted she doesn't even drink beer, she eventually gave him to the "peer pressure".

As for Kris' keg stand performance, Kourtney responded, "Watching my mom do a keg stand is probably one of the highlights of my entire life."
