Justin Timberlake wasn’t kidding about bringing sexy back. The super-suave singer is juggling two of Hollywood’s hottest babes. Just last week, Scoop! reported that Jessica Biel flew to Sundance to join him, and it looked like J.T.’s fling with Scarlett Johansson was kaput. But over Super Bowl weekend, guess who kept Justin company in Miami? None other than ScarJo.

The former N’Sync-er arrived in Miami in the wee hours of Sunday and partied with Scarlett until 4:30 a.m. at a party hosted by Kid Rock, reports Us magazine’s Web site. They attended the Super Bowl and a postgame party together, leaving after 3 a.m. — and proceeded to hole up in her hotel room for hours.
