Nick Jonas and Selena Gomez Fuel Romance Rumours

Nick Jonas has fuelled rumours he's revived his romance with fellow Disney star Selena Gomez after the singer/actress was spotted accompanying him on tour.

The Jonas Brothers star, 17, who is currently playing a series of gigs around the U.S. with his new band, Nick Jonas and The Administration, reportedly dated Gomez in secret for nearly a year before parting ways last February.

And speculation is growing that they are an item once again after Gomez, also 17, was seen stepping off Jonas' tour bus with him ahead of a concert in Detroit, Michigan on Saturday.

The Disney star was later spotted in the crowd at the show with Jonas' father, Kevin Jonas Sr and also accompanied her rumoured boyfriend to a gig in Chicago, Illinois on Monday.

Jonas has dated another famous teen star, Miley Cyrus. That romance ended in 2007.
