Kourtney Kardashian is celebrating her 37th birthday in Iceland.
Sources told the website the trio are visiting so West can record a music video for his latest album, "The Life of Pablo."
Kourtney and Kim shared a number of posts on social media, including a group photo in front of an icy waterfall.
"Happy Birthday @kourtneykardash Thank you for always doing everything first so I can copy you! I don't know what I would do without you! I love you! Happy Birthday!" Kim captioned a throwback photo with her sister.
Kourtney also received birthday messages from mom Kris Jenner and sister Khloe Kardashian.Ex-partner Scott Disick didn't offer any public well wishes, but was spotted with Kourtney's half-sisters, Kendall and Kylie Jenner, at Coachella over the weekend.
"Happy birthday @kourtneykardash!! What would our family do without you?!?! This picture sums us up, even though I'm covered in chicken pox, you're still chillin by my side. I love you!!!" Khloe wrote.
The reality star revealed she's open to a possible reconciliation last week on the "Today" show.
"We're not getting back together right now, but I don't know what the future holds in life, in God's plan," Kourtney said. "But we're just doing our best to be the best parents."
Scott admitted he "would love to see" himself and Kourtney reconcile on Sunday's episode of "I Am Cait."
Kourtney and her family will return on "Keeping Up with the Kardashians" Season 12 on May 1.
