Wearing a sheer top that showed off her black lace bra, the mother-of-three was definitely dressed to impress the pop star, pairing her racy top with olive green track pants and Yeezy boots.

But the KUWTK star made sure to throw on a leather aviator jacket before stepping into the church.

This is not the first time the odd couple has been spotted together. Last month, they met up for a night out at the Peppermint Club in West Hollywood. They first made headlines in 2015 when they were spotted getting cozy at sister Kendall Jenner's birthday party following her breakup with longtime boyfriend Scott Disick.

“They have hooked up a few times, including recently. It happens in L.A,” a source told People magazine last year. “He has met her kids, but they don’t hook up around the kids. It’s on nights when she has help and is able to go out.”

The insider added, "Kourtney is great. Justin thinks it’s cool that she is older and hot. She isn’t clingy and has her own life. There are no bad consequences for Justin to hook up with her. She is very easy going and just makes it fun for him to be around her."

Justin isn't the only boy toy Kourtney has been linked to. The brunette beauty also reportedly dated male model Younes Bendjima after meeting in Paris.

"[Younes] has quietly sparked a relationship with Kourtney and really fancies her," a source said, before adding that while "they aren’t ready to go public… there’s a real chemistry between them."

Sorry, Scott. It looks like things are back on Kourt and the Biebs!
