Kourtney Kardashian and Travis Barker Double Date With Megan Fox and Machine Gun Kelly

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.
