Everything old is new again! Two past couples are reported to have hooked up again recently: Ashley Olsen and Jared Leto, and Kate Hudson and Justin Timberlake.

Ashley and Jared (who dated in 2005) allegedly got together at a party in L.A. last week, Us Weekly reports. "They looked like a couple and they were making out," a witness says.

And as for Kate and Justin, they're said to have rekindled the flame that originally sparked at her New Year's Party last year. Spies for Star say they have been hanging out ever since JT's GF Jessica Biel went to England to shoot a new movie. As "coincidence" would have it, Kate and Justin arrived at a club together on Friday and left just a few minutes apart later that night.
