Justin Timberlake and Jessica Biel: Back On?

Justin Timberlake and Jessica Biel broke up in March, but a source says their four-year romance hasn't fizzled out just yet. At least not completely.

The two are "quietly seeing each other again," says a source. "They have been talking the whole time and decided to give it another shot."

"Jessica really wanted to get back together with him and Justin realized that the single life is not what it's cracked up to be."

Another insider cautions that reconciliation won't be an easy ride and adds that for now, "they're just spending time together and taking things slowly."

Still, hopefully it works out for the best, if that's what they both want and it makes them happy. It's good they're trying to work on themselves.

The only downside? Fewer Mila Kunis rumors. Those were hot.
