An Upgrade For Timberlake

N'SYNC star Justin Timberlake is so serious about his engagement to actress Alyssa Milano that he's about to replace the "Charmed" star's current engagement ring with an even bigger one.

Milano already has a solitaire diamond ring, but Justin is insistent they go to the exclusive Harry Winstons's jewellers in New York to get a bigger sparkler.

The pair, who have been dating since March of this year are planning to throw a lavish engagement party next February.

And the young lovebirds are also planning to move in together. A friend says, "There is even talk of Alyssa and Justin getting a place in Hollywood together early next year."
