Kourtney Kardashian is allegedly not thrilled to learn that Scott Disick is dating again.

According to In Touch Weekly, Kardashian is not jealous of the fact that Disick has fallen in love with someone again.

Rather, her issue is that her baby daddy is once again dating someone who’s much younger than him.

A source told the tabloid that the Keeping Up With the Kardashian star is appalled and embarrassed by the thought that Disick’s girlfriend’s age is much so close to the age of their eldest child, Mason.

Disick and his new girlfriend, Amelia Hamlin have been making public appearances throughout the past couple of weeks.

They’ve been spotted dining at an Italian restaurant, strolling on the beach, and more. However, Kardashian isn’t allegedly thrilled and she’s not the only one that feels this way.

Hamlin’s parents, Harry Hamlin and Lisa Rinna, are allegedly convinced that their daughter’s relationship with Disick is just a phase.

Harry and Rinna also allegedly prefer their daughter’s ex-boyfriend, Mercer Wiederhorn because he likes family to them.

Meanwhile, Disick’s other ex-girlfriend, Sofia Richie, unfollowed Hamlin on social media after reports swirled that she’s dating Disick.

Lionel Richie’s daughter also unfollowed Hamlin’s parents and siblings on social media because she feels betrayed by everyone.

Disick and Richie split back in August. Back then, a source told E! News that they have been on and off for the past two months.

The insider said that Richie tried her best to make her relationship work after their initial breakup. But Disick officially ended things for good.

Following their split, the exes reportedly stopped talking to each other.

In related news, TMZ’s recent claims about Kardashian’s reaction to Disick’s love life were very different.

The publication said that Kardashian couldn’t care less about who Disick wants to date as long as he’s a good co-parent to her and a good dad to their three kids.

Kardashian and Disick’s relationship is also going strong as co-parents and they don’t like getting involved in each other’s relationships.

As for the Keeping Up With the Kardashians star, the mom of three has been single since her split from Younes Bendjima.

In a previous episode of KUWTK, Kardashian told her friends that she feels like she’s in a different place in her life and doesn’t feel the need to date.

She also said that she’s content with just hanging out with her friends because texting random guys are meaningless.
