Mariah Carey is waiting for Jermaine Dupri to invite her into the studio to
record a duet with his lover Janet Jackson.

Carey is such a huge admirer of the ‘All For You’ hit maker, she has given
producer Dupri’s collaboration concept the green light.

She tells MTV, “I love Janet. I’m a big fan. So if Jermaine has a concept,
we should go and write something.”
