If Mashonda’s Twitter Open Letter to alleged homewrecker A. Keys had you sitting on the edge of your seat, just wait until Swizzy’s soon-to-be former wifey gets word of this: Hip-hop supercouple Swizz Beatz and Alicia Keyshave sparked rumors they are set to move in together after they were spotted house hunting in lower Manhattan this week, Star Magazine snitches say.

Beatz, real name Kasseem Dean, confirmed he is dating Keys in May, after a long and messy split from Mashonda. The exes split in April 2008 after four years of marriage, and Mashonda filed for divorce in February.

Now Alicia, 28, and Swizz, 31, are reportedly taking their controversial relationship to the next level by purchasing a duplex penthouse.

“The place is amazing. It even has a 2,000-square-foot terrace… Alicia and Swizz were holding hands as they looked around for about 20 minutes,” says a spy.
