Have Nick Jonas and Selena Gomez split up?

Rumours are flying that Nick Jonas and Selena Gomez have split after a huge argument.

Insiders say the pair who have been dating on and off for  12 months have split after another massive argument.

“They had another huge argument the night of The Oscars,” one insider said.

“I think they are slowing [their relationship] down.”

During a radio interview Friday, Selena seemed to confirm the split, saying, “Nothing is going on with Nick Jonas.”
