NEW YORK (Billboard) - Rihanna's "Rude Boy" led Billboard's Hot 100 singles chart for a fifth week on Thursday, once again fending off runner-up "Nothin' On You" by B.o.B featuring Bruno Mars.

Joining the top 10 party in only its second week on the chart was Usher's "OMG," featuring will.i.am, which jumped four places to No. 10. The track is Usher's 15th top 10 and first since he topped the list with "Love in this Club" for three weeks in March 2008.

Train's "Hey, Soul Sister" held at No. 3 for a third week, while former No. 1 "Break Your Heart" by Taio Cruz featuring Ludacris rebounded two to No. 4 thanks to increased radio play. It swapped places with Lady Antebellum's "Need You Now." In between, Jason DeRulo rose four to No. 5 with "In My Head," the follow-up to his No. 1 "Whatcha Say."

Lady Gaga's "Telephone" featuring Beyonce fell two to No. 7, the Black Eyed Peas slipped one to No. 8 with "Imma Be," and Justin Bieber's "Baby," featuring Ludacris, was also down one, to No. 9.

Top debuts included Jack Johnson's "You and Your Heart" at No. 20, and Jamie Foxx with the star-laden "Winner," featuring Justin Timberlake and T.I, at No. 28.
