Scott Disick is a single man for the first time in years, but he may be regretting his break up with longtime girlfriend Kourtney Kardashian.

Attending his friend JJ Corsini's wedding on Saturday, Disick shared a photo from the table and his place card, which read, "Scott Disick Guest." But his caption spoke the loudest about his current state of mind.

"When u realize the grass isn't always greener," he wrote.

The party boy still supported his best friend, saying he "couldn't be happier" for the groom.

Disick caught up with Kourtney for the first time on July 23 when they met for lunch with their three kids Mason, 5, and Penelope, 2 (it was unclear if their 7-month-old son Reign was there). The kids then spent more time with their dad after the meal at the Beverly Hills Hotel.

In his first public appearance at the 1Oak in Las Vegas, Disick told Entertainment Tonight that he was taking life "one day at a time."
