The former NBA player seemed "scared" when he and his ex-wife reunited for the first time in nine years during the season 6 premiere of 'The Kardashians'

Lamar walked into Khloe’s house with a bunch of red roses for the first time in years. They first married in 2009 after dating for just one month, before initially separating in 2013. Khloe and Lamar then got back together and didn’t finalize an official divorce until 2016, which was a result of his infidelity and substance issues at the time.

For years, this was such the love of my life that to learn how to unlove someone, to have to go through all that, it’s almost like a death,” Kardashian said.
