No jealousies here!
So what does the 26-year-old Goodrem have to say about the 18-year-old JoBro's former flame? And more importantly, what does Cyrus think of Goodrem?
"Delta loves Miley; she's a big fan of her music," an Industry insider (who knows all parties involved) tells us. "But Miley doesn't even know who Delta is. She's too busy getting ready for her Australian swing of her Gypsy Heart tour in June."
And besides, who needs a JoBro when Miley can have a movie star boy-toy?!
But the source insists all is cool and calm between the ladies—uh, yeah, especially since one doesn't even know who the other is!
"There is no bad blood whatsoever," adds a JoBro camper. "Delta had admired what Miley has accomplished at such a young age long before she met Nick earlier this spring."
But despite the eight-year age difference between Jonas and Goodrem, our music spy tells us the two honeys have bonded over their respective health challenges: Nick, 18, is diabetic, while Goodrem battled lymphoma at age 18.
Delta and Nick also share an obvious love of music, and it appears their collaborations have been both professional as well as personal.
Check out this twitpic Goodrem posted in March with the caption, "Loved creating with the incredibly talented @nickjonas and @greggarbo x," despite the two only making their affections public last week.
Let's just hope this ends better than Joe Jonas' past few relationships!
