Timberlake Romancing Alyssa Milano?

Justin Timberlake has been romantically linked to yet another celebrity, actress Alyssa Milano.

The 'N Sync frontman, 21, who has been seen with Janet Jackson, Alicia Keys and dancer Jenna Dewan since his split from Britney Spears earlier this year, has been spending a considerable amount of time with the 29-year-old former "Charmed" star.

On August 24th, Milano spent much of the day hanging out in Timberlake's trailer as he made the video for his debut solo single "Like I Love You." And sources close to 'N Sync say that something is definitely going on between the pair.

While Milano's representative has no comment, Timberlake's publicist Ken Sunshine simply chuckles, "He's 21 years old, God bless him."
