All eyes (and ears) are on Scott Disick as we wait for his response to Kourtney Kardashian and Travis Barker's engagement, but he is reportedly not pleased with the news.

An insider close to PEOPLE revealed that the E! reality alum’s ex, who she split from in 2015 after nine years of dating, is “not happy about the engagement.” "Scott never approved of Kourtney dating Travis. He has struggled with their relationship," the insider revealed to the celebrity gossip outlet. "He always had this idea that he and Kourtney would eventually get back together. He was pretty shocked when he found out that she was dating Travis.

As you know, the blink-182 drummer proposed to the Poosh mogul on Sunday (October 17) at the Rosewood Miramar Beach Hotel in Montecito, California, which followed an official announcement from the Kardashian via Instagram. "Forever @travisbarker," she captioned the big moment. According to a Kardashian family friend, the sunset proposal was "a complete surprise," despite Barker letting her family in on the secret. "The Rosewood is their favorite for short weekend getaways. They often stay at the hotel. This is why Travis proposed there. It's a very special place to them, but it was also easier to keep everything a secret by proposing there," the source explained.

Word of the duo's pairing surfaced in January, with the two taking their steamy romance to the forefront with glimpses for the paparazzi, social media interaction and even award show appearances. However, it was built on friendship as the two have reportedly been in touch for years.
