The cleavage-baring duo put on their best smoldering supermodel stares and aimed them at the mirror through thick layers of makeup.
Kourtney captioned the sister-act snapshot: ‘thank you for all of the love and support on our KOURT X KYLIE collab! RESTOCK today at 3pm pst’.
Samantha Armytage of the Australian breakfast show Sunrise pointed out this Thursday that the KOURT X KYLIE debut happened to occur right around the time Kourtney jetted to Washington, D.C. to push for new makeup regulation.
‘She’s supporting the bill that will require companies to disclose their ingredients to the FDA and change legislation that has not been updated in 80 years,’ said Samantha. ‘But it wouldn’t be a true Kardashian event without a plug, timing the launch of her makeup collaboration with sister Kylie around her advocacy.’

Khloe’s sister Kim swung by The Ellen DeGeneres Show this week and said of Tristan’s infidelity, which DailyMail.com exposed less than 48 hours before True was born: ‘Like, I don’t even know how to describe it besides it’s just so f***ed up.’
Wearing a skirt from her husband Kanye West’s line Yeezy, the sex tape icon said she would ‘try not to say anything so negative, ’cause one day, True is gonna see this.’
