News on Christina Aguilera, Lil' Kim, Mya, Pink, Lionel Richie, Popstars

'LADY' FLASH: All four of the artists involved with the new version of "Lady Marmalade" have been in the top-10 of The Billboard Hot 100 before, although some have been there more than others. The Interscope album track (from the soundtrack tom the forthcoming film "Moulin Rouge") leaps 19-10 in its fourth chart week.

- It's the fifth top-10 hit for Christina Aguilera, who has only missed the top-10 with her Christmas song and her duet with Ricky Martin.

- It's the second top-10 hit for Lil' Kim, who peaked at No. 6 in 1997 with "Not Tonight," a recording that featured even more artists than "Lady Marmalade" -- including Da Brat, Left Eye, Missy "Misdemeanor" Elliott, and Angie Martinez.

- Mya collects her third top-10 hit, following "It's All About Me" (No. 6 in 1998) and "Case Of The Ex (Whatcha Gonna Do)" (No. 2 in 2000).

- Pink is working her third top-10 hit, too. "There You Go" went to No. 7 and "Most Girls" reached No. 4, both in 2000.

Should "Lady Marmalade" go all the way to No. 1, it will be the first No. 1 hit for Lil' Kim, Mya, and Pink. Aguilera will pick up her fourth chart-topper, following "Genie in a Bottle," "What a Girl Wants," and "Come on Over Baby (All I Want is You)."

RICHIE'S RETURN: After an absence of five years, Lionel Richie is back on The Billboard Hot 100 with "Angel" (Island), an album track that shares the same title as another album track on the chart, the former No. 1 hit by Shaggy featuring Rayvon on MCA. Richie was last on the Hot 100 in 1996 with "Don't Wanna Lose You."

It's been almost 20 years since Richie made his first appearance on the chart away from the Commodores. "Endless Love," his duet with Diana Ross, debuted the week of July 11, 1981.

POPSTARS EXCEL: The Popstars' attempt at world domination continues. After topping charts in Australia, Germany, and the U.K., and reaching the No. 1 position on Billboard's Hot 100 Singles Sales chart, another Popstars group has shot to No. 1. The group put together on the Swedish edition of the TV series are on top in Sweden, according to "Chart Beat" reader Fredrik Gustafsson. The group is called Excellence, and they enter the chart in pole position with "Need To Know (Eenie Meenie Miny Moe)" (Bonnier/Virgin), succeeding Roxette's "The Center of the Heart."
