The 'Glee' actress - who was catapulted to the spotlight for her portrayal of Santana Lopez in the hit series - and the rapper have ''called their wedding off'' after getting engaged six months ago, and she took to Twitter to vent about him stealing an expensive watch because she's ''making more money'' than him.
In a post which has since been removed, she wrote: ''@BigSean stealing rolexes from a lady's house now. Maybe cuz I'm on Glee and making more money or something. #triflin' (sic)''
The hunk - real name Sean Anderson - hasn't responded directly to the accusations, but sources told website TMZ.com, the watch belonged to Sean but gave it to the screen beauty to wear although it wasn't her own to keep.
Rumours have been circling that he's been unfaithful to Naya, but sources have hit back at speculation which they claim is ''100 per cent false''.
They allege Sean decided to call off the wedding because he felt Naya was ''too controlling'' and became jealous of other women who he was working with.
A spokesman for the rapper said ''it is still his hope that they can continue to work through their issues privately''.
