After achieving the second-biggest leap in Billboard Hot 100 history last week, Fergie’s “London Bridge” ascends four rungs to the top of the chart.

The cut ends the six-week run of Nelly Furtado’s “Promiscuous” featuring Timbaland, which falls to No. 3. Gnarls Barkley’s “Crazy” holds at No. 2.

Elsewhere on the Hot 100, Cassie’s “Me & U” descends from No. 3 to No. 4, the Pussycat Dolls’ “Buttons” featuring Snoop Dogg jumps 6-5, and Beyonce’s “Deja Vu” featuring Jay-Z slides 4-6.

Sean Paul’s “(When You Gonna) Give It Up to Me” featuring Keyshia climbs 12-7 and is the Hot 100’s greatest airplay gainer. Christina Aguilera’s “Ain’t No Other Man” warms the No. 8 spot, Yung Joc’s “It’s Goin’ Down” drops 7-9, and Panic! At the Disco’s “I Write Sins Not Tragedies” soars from 15th spot to No. 10 to round out the Hot 100 top tier.
