Showing support! Khloé Kardashian gushed over Hailey Baldwin and Justin Bieber‘s sweet relationship, and it looks like they all have a lot to be grateful for. The oldest Kar-Jenner sister, Kourtney Kardashian, was rumored to be hooking up with the Biebs back in 2016, but the pop star has remained a very close friend of the Keeping Up With the Kardashians family.

“Thankful for the love of my life,” the 23-year-old model captioned a sweet photo of the two kissing on their wedding day back in September.

Khloé, 35, swooned over the adorable black-and-white photo and commented, “OMG, you guys are the cutest.” She wasn’t the only famous face to respond to the lovey-dovey post. E! host Jason Kennedy added, “Just precious.” Celeb makeup artist Morgane Martini echoed, “Gorgeous couple.”

Rumors started flying about Kourtney, 40, and Justin, 25, back in 2016 when they were spotted partying together — the reality starlet was later seen leaving the Montage Beverly Hills hotel at 4 a.m. After the questionable hangout, the Poosh founder told Ellen DeGeneres in January 2016 that they were “friends.”

The “What Do You Mean” singer gave a cryptic response when asked about the rumors later that month. “I’m being used, man,” he said on The Bert Show. “What can I say?” When asked to elaborate on his relationship with the brunette beauty, he added, “Nah, we’ll leave it at that … But for real, she’s great. I’ve known [the family] for years.”

Time has passed and the pop star has been happily married to Hailey — one of Kendall Jenner‘s BFFs — for over a year. Although the two had a few bumps in the road, the blonde bombshell confessed that the newlyweds have found their groove. “Now it’s easier because we’ve found a rhythm. We have more fun together, which is what should happen when you spend more time with someone you love,” she divulged to Australian in an article published on September 15.

What’s the key to a healthy relationship in Hailey’s opinion? “Compromise,” she told the outlet. “If you don’t want to compromise, you can’t be in a relationship.”

Keep being the cutest, you two!
