'Call Me Maybe' has now spent seven weeks at No.1 in America - with 'Born This Way' spending six at the top in 2011. Lady Gaga issued a mock threat to Carly Rae Jepsen on Twitter, which was both a cleverly disguised congratulations and a teaser for her upcoming material.
"@carlyraejepson (sic) I SEE you just swooped in and broke my BORN THIS WAY record of the most weeks at #1.," Gaga tweeted. "DONT GET COMFORTABLE IM COMING FOR YOU"
Lady Gaga last week premiered new track 'Nothing On (But The Radio)' to a handful of fans from her car. The track is thought to be a new version of a 2010 demo.
Carley Rae Jepsen was last week in the centre of two potential sex scandals, as a sex tape was said to feature the star - before photos of the star were said to have been stolen from her home computer.
