As mentioned in a breaking news story yesterday, B.o.B moves into the No. 1 slot on the Billboard Hot 100 with his debut single "Nothin' On You," featuring Bruno Mars. The rapper is the fourth male vocalist since October to reach No. 1 with his first entry, following Jay Sean, Jason Derulo and Taio Cruz. It's the fastest chart-topping clip for rookie men on the Hot 100 since Chris Brown, James Blunt, Ne-Yo and Daniel Powter each crowned the list between November 2005 and April 2006.

B.o.B also scores the chart's Hot Shot Debut as "Airplanes," featuring Hayley Williams of Paramore, lands at No. 12. That track and the just released "Bet I" - which should hit the Hot 100 next week - were digitally released in advance of his debut album, "B.o.B Presents: The Adventures of Bobby Ray," which reaches retail on April 27.

"Not Myself Tonight," Christina Aguilera's first single from her upcoming "Bionic" album (due June 8), moves 77,000 downloads and enters the Hot 100 at No. 23 to become the singer's third-highest Hot 100 debut. Only "Keep Gettin' Better" (No. 7, 2008) and "Ain't No Other Man" (No. 19, 2006) posted better starts. At radio, "Not Myself Tonight" improves 27-23 in its second week on Pop Songs.

Owning the next four debut slots on the Hot 100 are the latest singles from the Glee Cast, performed during the April 13 episode of the FOX series. The troupe's covers of "Gives You Hell" (The All-American Rejects), "Hello" (Lionel Richie), "Hello Goodbye" (The Beatles) and "Hello, I Love You" (The Doors) enter at Nos. 32, 35, 49 and 66, respectively. Collectively, the debuting tracks move 245,000 downloads, while a fifth track, its rendition of AC/DC's "Highway to Hell" shifts an additional 22,000, while falling just shy of the chart.

Since the start of 2009, the Glee Cast has now posted more chart entries (29) than any other act, surpassing Lil Wayne's 25 debuts during that span. And the act didn't post its first title on the list until June of last year. Expect more Glee Cast debuts next week as titles from the episode and album "The Power of Madonna" are currently selling at a brisk rate.

Moving back to the action within the Hot 100's top 10, Rihanna's "Rude Boy" is bumped to No. 2, but retains its lead on Radio Songs with 154 million listener impressions. Train's "Hey, Soul Sister" (No. 3) and Taio Cruz's "Break Your Heart" (No. 4) both hold in place.

Lady Antebellum's "Need You Now" (6-5) and "In My Head" from Jason Derulo (5-6) swap spots, remaining ahead of "Telephone" by Lady Gaga featuring Beyonce, which holds at No. 7.

Usher's "OMG," featuring, makes a 10-8 move in the congested top 10, earning Airplay Gainer accolades with an impressive 17 million listener impression increase, good enough for a strong 56-25 push on the Radio Songs tally.

Ke$ha's "Your Love Is My Drug" shoots up 19-9, the third top 10 single from her debut set "Animal." Top 40 radio play (18-13 on Pop Songs) and a short one day of retail carry-over from her April 17 appearance on "Saturday Night Live" prompt a digital spike of 47% (13-7 on Digital Songs with 124,000 downloads). Ke$ha topped the Hot 100 for nine weeks earlier this year with "TiK ToK" and took "Blah Blah Blah," featuring 3OH!3, to No. 7.

Closing out the top 10 is Adam Lambert's "Whataya Want from Me" which rises 23-10 on the heels of his "American Idol" mentoring stint, which included a performance of the track. Exposure on the FOX network ratings juggernaut results in the Digital Gainer award and a 29-8 move on Digital Songs, with sales more than doubling to 108,000.

The remaining two debuts on this week's Hot 100 belong to two current top 20 titles on Country Songs; Jason Aldean's "Crazy Town" (No. 92) and Brad Paisley's "Water" (No. 100).
