The Saturdays set to top the charts

According to Marvin from JLS The Saturdays are set to score the first ever No.1 single this summer

The girls are getting ready to comeback with new material and Rochelle's boyfriend Marvin has already heard their new single, Notorious.

"Me and JB went down to the shoot in LA a couple of weeks ago." said Humes in an interview "The new single is wicked...I think this could possibly be the girls first No 1.

"The girls are releasing before us so we're not going to have any boyfriend/girlfriend battles in the chart - no way"

All we know at this stage is that the track contains the lyrics "I'm an outlaw/ I'm the big boss/ I'm a gangster/ on the dance floor," it reads.

The single is written by Ina Wroldsen, who has previously worked with the group on 'If This Is Love' and 'Up',
