Kourtney Kardashian is the only married member of the famous family right now and is wondering if her sisters will ever find the kind of happiness she has with Travis Barker – while urging them to keep the faith and not give up on their own happily ever after.

“Kourtney is so pro-relationship right now,” a source exclusively tells In Touch. “She feels like Travis was an answer to her prayers and says she’s never known happiness and peace like this in her life. Of course, she wants that for everyone in her life, her friends and her family.”

Kourtney, 45, confirmed she was dating Travis, 49, in February 2021 after years of being close friends. After getting engaged in October 2021 and tying the knot just one year later, the Poosh owner has been in her own little love bubble, especially after welcoming their first son together in November 2023. Kourtney wants the same for her siblings, Kim Kardashian, Khloé Kardashian, Robert Kardashian, Kendall Jenner and Kylie Jenner — however, it “comes across a bit annoying” for those who aren’t in relationships.

“She’s basically saying that life with the right relationship is ten times better than without. But there’s no denying that is how she feels,” the insider explains. “She says her marriage has brought her so much stability and comfort and she’s telling her sisters not to judge love based on their past experiences.”

Her wedding with Travis marked Kourtney’s first time down the aisle. The Hulu personality is most well-known for her turbulent romance with Scott Disick. The pair dated on and off from 2006 to 2015, during which they welcomed three children — Mason, Penelope and Reign. Their relationship was fraught with significant challenges, including infidelity and Scott’s struggles with substance abuse.

“If she were to do that and base her expectations off of what she had with Scott, she’d be nowhere,” the insider explains. “But she opened her heart to love and let it in when Travis came around, and now here she is, happier than ever. In her view, her sisters need to do the work to re-open their hearts and let go of the baggage so that a good man like she has, can come into their life.”

Things are going so well for Kourtney and Travis that a separate source exclusively told In Touch last month that the A-listers were considering growing their family again with a surrogate.

“Kourtney has been very open about wanting another baby with Travis and they are trying the old-fashioned way pretty much non-stop. But if that doesn’t work this time, using a surrogate is on the table,” the source said at the time. “It’s worked out well for Kim and Khloé, so Kourtney has seen all the positives firsthand.”

Kourtney has Travis’ “full support” and is “hoping for a girl this time.”

The source added, “They both think having twins would be a huge plus, either a boy and a girl or twin girls. The exciting thing is if they do use a surrogate, that’s actually totally doable. Nothing is in the works yet, and for now, they’re still hoping to do this naturally, but if not, they will turn to science for help.”
