Kardashian and Disick split last summer after nearly a decade of dating -- and after he was spotted out with another woman -- but have been sparking rumors of a reconciliation lately.
"We're not getting back together right now, but I don't know like, what the future holds in life," Kardashian played coy during a recent episode of the Today show. "We're just doing our best to be the best parents...We're friends at this point."
While Disick doesn't appear to be in Iceland for the b-day festivities -- he was partying with Kylie and Kendall Jenner over the weekend at Coachella -- he did join the family on a recent trip to Vail, Colorado.
