Lady Gaga Tops MTV European Music Awards

Rihanna performs during the MTV Europe Music Awards 2010 live show at La Caja Magica on November 7, 2010 in Madrid, Spain.

Two weeks after topping the Billboard Hot 100 with "What's My Name?" (featuring Drake), Rihanna will return to No. 1 on the chart released Thursday (Nov. 25) with "Only Girl (In the World)," the debut single from her new album, "Loud."

It's the first time in Hot 100 history that an album's debut single reaches No. 1 after the second single does. "What's My Name" dips 7-8 on the Hot 100, though it does take the Airplay Gainer for a fourth straight week. "Loud, meanwhile, debuts at No. 3 on the Billboard 200.

"Only Girl" is Rihanna's fourth single to ascend to No. 1 in 2010, making her the first female, and first artist overall since Usher in 2004, to hit the top that many times in a single calendar year. Rihanna also moves to the forefront for most No. 1s in the millennium (since 2000), as "Only Girl" is her ninth track to lead the list. She had been tied with Usher for the past two weeks, with eight chart-toppers since 2000.

The latest "Glee" episode, titled "The Substitute," brings only a pair of titles by the cast onto the Hot 100, each one featuring guest vocals by Gwyneth Paltrow. Coming in at No. 11 as the Hot Shot Debut is the "Glee" Cast's version of Cee Lo Green's "Forget You," while "Singing in the Rain/Umbrella" debuts at No. 18.

After topping Digital Songs for the first time last week with its cover of "Teenage Dream," the ensemble goes for back-to back No. 1s, as "Forget You" debuts atop that chart with 192,000 downloads, according to Nielsen SoundScan. "Rain/Umbrella" shifts 140,000, while Green's own "F**k You (Forget You)" is lifted into the top 10 of the Hot 100 for the first time, on the wings of the "Glee" Cast cover. The original recording, including its version with decidedly un-"Glee"-like language, is the top Digital Gainer, moving 191,000 (up 94%), a week after its previous best sale frame (98,000). The explicit version makes up 68% of the title's sales for this week.

Elsewhere in the Hot 100 top 10, P!nk celebrates the holiday week with a 4-2 lift for "Raise Your Glass," while Far*East Movement seems to have exhausted its No. 1 run, dropping to No. 3 after three non-consecutive weeks.

Ke$ha rebounds 6-4 with "We R Who We R," which debuted at No. 1 three weeks ago due to a huge opening week sales frame. Nelly's "Just a Dream" spends an eighth consecutive week in the top five, holding at No. 5.

Katy Perry streaks to No. 6 with "Firework," with the track showing a steady upward trajectory in its five weeks on the list (57-29-10-9-6). Bruno Mars dips 3-7 with "Just The Way You Are," while follow-up single "Grenade" explodes 30-17, improving more than 50% in both sales (up 58% to 100,000 downloads) and audience (up 51% to 37.1 million impressions). Rounding out the top 10 is Trey Songz, who holds onto the anchor spot for a second week.

Dr. Dre makes his first chart appearance as a lead act in more than 10 years, as "Kush," featuring Snoop Dogg & Akon debuts at No. 48. The song moved 45,000 during a partial week of sales. The last time the rap icon appeared on the list with his own track was when "The Next Episode" peaked at No. 23 in July 2000.

Akon also assists another chart legend this week, aiding Michael Jackson on the King of Pop's 48th Hot 100 hit, "Hold My Hand," which debuts at No. 84. Akon also appeared on Jackson's last charting effort, "Wanna Be Startin' Somethin' 2008," which peaked at No. 81 in February of that year. Jackson's new track sold 19,000 in less than three days of availability as it reached digital retailers on Friday, Nov. 19.
