Scott Disick has been a perennial favorite for many Kardashian fans.

Last week, news broke that his ex-girlfriend of three years, Sofia Richie, had gotten engaged.

In response, Disick took to Instagram to make light of the situation, posting a photo of himself on a boat in Miami with the caption, "Call me Good Luck Chuck in 305."

The joke was a reference to the 2007 romance film Good Luck Chuck, starring Dane Cook. Basically, it's a very good joke.

"Scott is happy for Sophia and has moved on from their relationship," a source told "Entertainment Tonight." He posted on Instagram with the caption Good Luck Chuck because he was tagged in a post about Sofia and Courtney's engagement and wanted to make a joke about it."

The source added, "Scott is definitely still heartbroken about Courtney, and it's still hard for him to see her with Travis."

Richie is engaged to Elliot Grainge and posted a beautiful shot of the proposal on Instagram with the caption, "Forever isn't long enough."

Kardashian, who has children Mason, Penelope, and Reign with Disick, became engaged to partner Travis Barker in October. She also announced the happy news via Instagram, writing simply, "Forever."

Disick reportedly had a hard time accepting Barker as a part of his life, but is doing what is best for his children.
