Inside Kourtney Kardashian and Travis Barker's Date Night With Megan F

Kourtney Kardashian and Travis Barker attended UFC 260 in Las Vegas on Saturday night with Megan Fox and Machine Gun Kelly. A source tells ET that they are all good friends and have had many double date nights. The 41-year-old Poosh founder and the 45-year-old Blink-182 drummer have been dating for a few months and things seem to be getting serious. After Barker recently shared a video of his new tattoo, fans began speculating the ink was a tribute to the ‘Keeping Up With the Kardashians’ star.
