MILEY CYRUS may be wearing her engagement ring again, but sources say she was hanging out with her ex NICK JONAS on Monday.
--They were spotted at a restaurant called Patys in Toluca Lake, California. One witness Tweeted, quote, "Miley Cyrus was at Paty's with Nick Jonas like 10 minutes ago. So cool."
--And another said, quote, "OMG, Miley Cyrus ordered some food right in front of me!! Nick Jonas was there too."
(--Miley was the inspiration for Nick's Jonas Brothers song "Wedding Bells". It's about a guy who doesn't want his ex marrying someone else.)
(--By the way . . . the not-always-reliable British tabloids say Miley's wedding is back on, but Liam Hemsworth wants her to GROW UP. You can read more about that here.)
