Who will rock the house at Sunday night’s Grammys? PEOPLE checks in on pop music’s big party, as well as other events to watch for in the coming week:

GOOD, CLEAN POP: Expect plenty of bodice-ripping parodies a la Janet Jackson and Justin Timberlake at the 46th annual Grammy Awards, airing on CBS Sunday night from the Staples Center in Los Angeles – complete with a video delay, so any unruly behavior can be censored. As of Friday, Ms. “Nasty” Jackson was not scheduled to attend (despite an earlier report to the contrary), but her partner in crime, nominee Timberlake, will be there as well as Madonna, Queen Latifah, the White Stripes, Alicia Keys and 50 Cent. Other highlights: an all-star funk-fest with OutKast and Earth, Wind & Fire, and a tribute to the 40th anniversary of the Beatles’ first U.S. TV appearance, featuring Sting and Dave Matthews.

DIANA’S PLEA: Diana Ross will be phoning in her appearance Monday, Feb. 9 at Tucson City Court, for a hearing to determine the terms of her plea deal connected to a December 2002 drunk-driving bust. The Motown legend was arrested on three DUI-related charges when she was pulled over while traveling the wrong way on a street and registered a .20 percent blood-alcohol level (Arizona’s legal limit is .08). Though the former Supreme initially pleaded innocent, Ross recently agreed to accept a plea bargain.

OSCAR MIXER: It’s the ultimate celebrity meet-and-greet, as this year’s Oscar contenders congratulate themselves at the annual Academy Awards nominees luncheon at the Beverly Hilton on Monday, Feb. 9. Perhaps Best Supporting Actor nominees Tim Robbins (“Mystic River”) and Alec Baldwin (“The Cooler”), and Best Actor nominee Sean Penn (“Mystic River”) will talk politics, while Best Actress nominee Charlize Theron – who packed on over 30 lbs. for her “Monster” role – will exchange weight-gain secrets with Best Supporting Actress nominee Renee Zellweger (“Cold Mountain”). Sure to be cooed over: Kiwi actress Keisha Castle-Hughes, the 13-year-old star of “Whale Rider” and the youngest Best Actress nominee in history.

DON’T BLAME CANADA: Conan O’Brien had better bundle up. The NBC “Late Night” host will be heading to the Great White North, taping his show from Toronto on Tuesday, Feb. 10 through Friday, Feb. 13. Why leave his cushy seat at Rockefeller Center in New York? To help the city recover economically from the effects of the SARS virus. Welcoming him to Canada will be Canuck guests including Jim Carrey, Mike Myers, “Will & Grace”‘s Eric McCormack and Michael J. Fox, who also makes his return to prime time as an obsessive-compulsive doctor on the Tuesday, Feb. 10 episode of NBC’s “Scrubs.” (He’ll also appear a week later, on Feb. 17.)

AND FINALLY… With the censors on full alert, don’t expect much stripping from Christina Aguilera at the 53rd NBA All-Star Game. The diva will, however, sing the national anthem at the event, which will be broadcast live on TNT Sunday, Feb. 15, from the Staples Center in Los Angeles.
