Carly Rae Jepsen is enjoying her fourth week at number one on the Billboard US Hot 100 with her worldwide smash 'Call Me Maybe'.
The 26 year-old singer also scored the week's highest new entry in America, with her Owl City collaboration 'Good Time' entering the chart at number 18, just one day after the two shot the song's music video together in New York City.
Maroon 5 had another successful week in the US with their latest single 'Payphone' remaining strong at number two, while fourth studio album 'Overexposed' entered the Billboard Top 200 album chart at number two after selling 222,000 copies in a single week, according to Nielsen Soundscan.
'Moves Like Jagger' stars Maroon 5 recently spoke out about the direction of their latest record and said they have embraced their pop roots on the record, and the Adam Levine-fronted group released a music video for their next single 'One More Night' last week.
The only other new entry in this week's US singles top ten comes from David Guetta with his Sia featuring hit 'Titanium' jumping up the chart to number nine to give the 'Where Them Girls At' producer his fifth Hot 100 top ten hit.
