The singer has been busy designing her Mariah Kiss Kiss underwear collection, which will hit stores in 2005.
A friend of Carey enthuses, "Mariah will market the sexy undies after her next album release in June and she can't wait.
"They will be designed for women of all shapes and sizes."
Lopez released her intimates range earlier this year, two years after launching her J.Lo By Jennifer Lopez clothing collection.
Rumor has it that, based on the lack of success of J. Lo's line, and the concerns about a similar situation with Carey's Kiss Kiss wear, they will be merging the lines...
...they'll call it Kiss Lo...
...and the side story is Bill Clinton might come on board as an additional endorser.
