Keeping up with the Kardashians is a full-time job for their "momager" Kris Jenner. Jenner was on 'Good Morning America' (Weekdays, 7AM on ABC) Tuesday discussing her role as part mom, part manager, to the Kardashian girls. She not only has to mediate infighting between her daughters, but also has to deal with gripes directed her way if one or more of the kids thinks she's being treated unfairly.

One of the clips from the segment showed Kris announcing she had secured a perfume deal for Kim. That miffed Khloe. "You get Kim her own deal first, and then it's the three of us?" she said. "I will sue the [poop] out of you." Kris asked her, "Are you insane?"

Daniel Radcliffe has already filmed the last installment of the 'Harry Potter' franchise, 'Harry Potter and the Deathly Hallows Part 2,' which hits theaters July 15. Lara Spencer reported Tuesday on 'Good Morning America' (weekdays, 7AM on ABC) that Radcliffe has also quit drinking, according to an interview in GQ magazine.

"He has just told GQ magazine that he is no longer drinking alcohol after partying quote 'unsuccessfully,'" she said. "He said he began drinking in 2009 while shooting 'Harry Potter and the Half Blood Prince' and realized he was relying on alcohol too much."

Spencer also marveled that the paparazzi never managed to catch Radcliffe with a drink in his hand. It helps if you have a cloak of invisibility to hide your hooch.

Cirque du Soleil doesn't just take anyone off the street who can do strange, bendy things in the air. It takes a lot of time, hard work and dedication, as Lara Spencer found out Tuesday on 'Good Morning America' (weekdays, 7AM on ABC). Spencer put herself through aerial training and took a spin on the "Wheel of Death" with the cast of 'Zarkana,' Cirque du Soleil's new show in New York City.

"It's one thing to play dress-up in the Cirque performer's clothing," said Spencer. "It's quite another to walk in their shoes." Spencer had a little trouble with a spinning-hoop stunt. "Even barely moving, I'm dizzy and dazzled by the difficulty of this trick." She did a bit better with a wire-aided backflip.

The main stunt was the aforementioned "Wheel of Death," which looks like two hamster wheels spinning on an axle suspended above the stage. Spencer went three rounds with that but didn't like it one bit. If they need another woman for the show, Spencer thinks Robin Roberts would do nicely.
