After a whopping 18 months of snogfests and Scrabble tournaments, Justin Timberlake and Jessica Biel are shacking up!

The Easy Virtue beauty has already begun the slow & painful process of stuffing everything she owns into neat little packages which will soon find themselves in the “Chop Me Up” singer’s humble abode.

“Jessica is preparing to live in Justin’s Hollywood Hills home,” a source told In Touch Weekly. “They’re both really excited. They’re definitely headed for marriage. Moving in is just the beginning.”

Because Biel will be taking up residence in Justin’s stunning 6-bedroom crib, she has decided to hand over her Brentwood-district dwelling to her family as “…she doesn’t want to sell it.”

Remember last month when we reported a possible engagement? Well that plan appears to be moving full steam ahead as Timberlake was spotted at the jewelers, again!

“Justin has been ring shopping, and we’re talking serious, major Harry Winston-type shopping here,” a close acquaintance of Biel’s slipped to the Chicago Sun Times. “He has been quizzing Jessica’s closest pals and associates, trying to get a take on the kind of engagement rings she has admired.”

“The only comment I ever heard Jessica make was when she complimented a mutual friend’s square-cut emerald ring - when a girlfriend of ours got engaged,” the insider continued.  “It was huge!”

Good thing Justin isn’t strapped for cash; somehow I doubt Biel would say ‘yes’ to a Cubic Zirconia!
