"He picked her up from the charity event," the source tells Us.

The reality star, 28, began dating Bush, 24, the running back for the New Orleans Saints, in April 2007. Although her split with the football player -- who was in town for NFL training camp -- was amicable, her siblings have said they want to see a reunion.

"I haven't talked to him, but my mom just said she's going to training camp and dragging him back!" Kourtney, now pregnant with her first child, said earlier this month. "We all love Reggie. How cute would the babies be?" When asked if they will get back together, the 30-year-old reality star said, "I hope so."
