Rihanna candidly talks about Chris Brown

In an interview that airs Thursday on "Good Morning America," Rihanna opens up to ABC News about being assaulted by Chris Brown earlier this year. "This happened to me. ... It can happen to anyone," RiRi, 21, tells Diane Sawyer . About Brown, Rihanna tells Sawyer, "He was definitely my first big love." The interview will continue Friday on "20/20." In an interview with the December issue of Glamour, meanwhile, Rihanna explains the media scrutiny of her life following the assault as follows: "I went to sleep as Rihanna and woke up as Britney Spears ." (In a related story, don't be surprised if Kevin Federline is now bragging to friends that he slept with Rihanna.) Rihanna's fourth album, "Rated R," is due in stores Nov. 23.

Carey makes Leno want furniture back on his show

Mariah Carey appeared on "The Jay Leno Show" on Monday and nearly took a spill as she stumbled during her entrance on her way to her seat. She kept her balance and made light of her near-gaffe, but that wasn't it: The buxom singer, wearing a revealing, low-cut black dress, looked as if she were going to fall out of her dress at any minute during her interview. After Carey stood up and bent over in front of Leno while demonstrating how she puts on her perfume -- dabbing her cleavage with a bottle of her fragrance -- a shocked and awed Leno made a funny: "It's times like this I wish I had the desk," he said.

'30 Rock' fails in German debut

Jay Leno may be in the ratings basement at NBC, but at least he's doing better than "30 Rock" is doing in Germany. The Emmy-winning Tina Fey sitcom premiered on German TV Sunday night and scored a jaw-dropping 0.0 rating, meaning fewer than 5,000 viewers tuned in, according to the Hollywood Reporter. "30 Rock" was to be the flagship of the country's ZDFNeo network, but it looks like Tracy Morgan doesn't play to Germans quite as well as David Hasselhoff . On the bright side, "30 Rock" still did better than its lead-in, a rerun of "The Byron Allen Show."

• Alec Baldwin and Steve Martin will host the 2010 Academy Awards together, Oscar producers announced Tuesday. It will be Martin's third time hosting and Baldwin's first. Here's to hoping they do "SNL" together as a warm-up.

• Lady Gaga -- coming to Detroit for two shows Jan. 12 and 13 -- netted her fourth No. 1 on Billboard's Pop Songs chart with "Paparazzi," making her the first artist in the chart's history to notch four No. 1 songs from a debut album. Quick, name the other three songs. Give up? They are "Just Dance," "Poker Face" and "LoveGame."
