Nick Jonas was spotted with Australian singer Delta Goodrem at the ArcLight in Hollywood on Sunday, and we're not sure if they're officially a couple, but here's what we know: there is a HUGE age gap between the two!

Nick turned 18 last September and Delta is 26, which is much older than some of the other ladies he's dated, like teen superstars Miley Cyrus and Selena Gomez.  Just last month Goodrem and her fiance, 31-year-old singer Brian McFadden announced that their relationship was over, so it seems like she's dipped into a far younger dating pool for her rebound!

On Sunday night Nick tweeted, "I feel so blessed. Had a great weekend," and while he has yet to comment on his relationship with Delta, Just Jared Jr. has a hunch that the two are just friends.  "JJJ is thinking it’s more of a business friendship. Nick could be writing and producing some tracks for Delta," the website writes.

Nick and Delta were joined by older brother Joe and several other pals for their movie date, and the middle Jonas sibling tweeted, “Go see Bridesmaids! Great movie. I wasn’t sure if I’d like it. But it was really funny.”
