Kourtney Kardashian & Scott Disick Relationship News Update 2015: Scott Regretting Breakup with Kourtney, Desperate to Attend Kylie Jenner's 18th Birthday Party?

It appears that Scott Disick is eager to be part of the notorious Kardashian-Jenner clan once again, after splitting with the mother of his three children, Kourtney Kardashian. He seems to be using social media to get back in their good graces and hopefully earn a golden ticket to Kylie Jenner's 18^th birthday bash.

On Friday, the 32-year-old Instagrammed a photo of his seating arrangement at a friend's wedding. His placement reads, "Scott Disick Guest," while the image is captioned, "When u realize the grass isn't always greener." It looks like he is pretty regretful about breaking up with his girlfriend of eight years; there is no doubt weddings are a terrible reminder of how lonely a party of one can be, especially with the smell of love so strong in the air.

However, could this all be part of a ploy to get an invite to the 18^th birthday party of the year? HollywoodLife.com revealed that Disick, despite the hardships between him and Kardashian, he still wants be part of the family -- he has seen Jenner mature over the years and wants to be part of this milestone in her life.

"Regardless of his problems with Kourtney, Scott has seen Kylie grown up and considers her family and wants to be there for her special day," a source said. 

The source also claimed that Disick has already asked his former girlfriend if he can come to the big event: "Obviously, he's approached the subject very carefully with Kourtney already, who said she will leave the decision entirely with Kylie."

Their source added that the teen is conflicted by the entire situation and wants to keep her party void of any squabbles, saying, "Kylie would love him to be there, but is also respectful of her older sister's current situation. It may be best to avoid any conflict at all by not inviting Scott to any birthday gatherings."

Jenner reportedly plans to celebrate the big bash in Canada, where it is legal to drink at the age of 18. She will have a blast at the Montreal Beach Club on Aug. 16. -- looks like Disick still has a few days left on the calendar to pull out a few more tricks before the super sweet soiree.
