When Kylie Jenner revealed she had given birth to a baby girl on Feb. 1, the world was both shocked and not shocked at all. It was reported ad nauseam that the Keeping Up With the Kardashians star was expecting her first child with boyfriend Travis Scott, and the sexy selfie queen disappeared from social media. Despite numerous reports that the duo was on the rocks during her pregnancy, the makeup mogul and rapper seem happier than ever. And after seeing the sweet video she posted documenting her pregnancy, everyone is wondering: When did Kylie and Travis start dating? Scroll down for a timeline of the lovebirds' relationship:

April 2017 — The First Sighting

Not long after Kylie split from long-time boyfriend Tyga, she was spotted with Travis at Coachella (where all young celebs go to meet and hook up). Initially, it was reported that the two were just friends and that Kylie was simply trying to make her ex jealous. But, when the pair was spotted a week or so later looking "super hand-holdy" at an NBA playoff game in Houston, it was obvious they were more than just buddies. Kylie also showed up at Travis' birthday party at the end of the month.

May 2017 — Making It (Somewhat) Official

Kylie posted a photo with Travis to Instagram. Granted, it was a massive group shot at the Met Gala (and Travis was hiding his face), but still. That pretty much made it social media official. The two also jetted off for a romantic getaway to Miami later in the month. Travis was playing at the Rolling Loud Festival, and the two still hadn't formally announced their relationship, but they were seen strolling around town arm-in-arm, so yeah. It was definitely on.

June 2017 — Cementing Their Love (With Ink)

In a somewhat surprising move, Kylie and Travis got matching butterfly tattoos. She posted photos of the his and her ink to Snapchat.

July-August 2017 — Groupie Vibes

Late summer was a busy time for Travis and his career, and Kylie was there to support him. In July, the 20-year-old was spotted with her sister Kendall and model Bella Hadid watching Travis perform at the Wireless Festival in London. In August, Kylie was seen checking out Travis' performance when he opened for Kendrick Lamar. After one of his August performances, Travis threw Kylie a surprise birthday party complete with an ice sculpture of her butt. #TrueLove. His other gift to her was reportedly a diamond necklace.
