Pharrell Williams to Marry Helen Lasichanh

Congrats to Pharrell Williams! Sometime when he's not busy turning Miley Cyrus into her urban persona, he's canoodling with Helen Lasichanh -- and now it's revealed that the pair are tying the knot!

Bossip reports that Williams and Lasichanh will become husband and wife on October 12, though other details are scant. What they do know? That the guest list is going to be stellar.

Jay-Z and Justin Timberlake are slated to perform at the bash, and the guest list includes Pusha T and Malice from Clipse, Robin Thicke and wife Paula Patton, Gwen Stefani and Williams' N.E.R.D. collaborator Chad Hugo.

Williams adores Lasichanh, describing every night of their relationship as a "sleepover" and referring to the beauty as his "bestie." Awww!
