Kylie Jenner has sparked engagement rumors after flashing a big sparkler on her left hand's ring finger.

The 20-year-old Life of Kylie and Keeping Up with the Kardashians star got people talking when she shared a Snapchat video on Saturday of herself driving to sister Kim Kardashian's cherry-blossom themed baby shower, Us Weekly reported.

The video zoomed into the Bentley vehicle's steering wheel, and at one point, Kylie moved her left hand over to the top of the wheel and then quickly showcased a huge rock on that finger.

Fans are speculating whether Kylie's boyfriend Travis Scott popped the question considering she's reportedly pregnant with his child.

Multiple sources told Us that the couple is anticipating the arrival of a baby girl in February 2018.

Kylie, however, has yet to address any of the pregnancy or engagement rumors directly.

According to TMZ, Kylie began telling her friends that she's expecting her first child in early September. Around the same time, Travis, a 25-year-old rapper, was reportedly telling pals that he has a baby girl on the way.

"The family has known for quite some time. She is REALLY excited and so is Travis!" an insider told People, which cited another source claiming in August that Travis treats Kylie with "a lot of respect and love" and she's "very happy" with him.

A source confirmed to Us in June that Kylie and Travis' romance was "serious" and they were "spending a lot of time together."

But this isn't the first time Kylie has faced engagement rumors. When the reality TV star was dating Tyga, she showed off a huge diamond ring in Fall 2016. Kylie allowed fans to think it was an engagement ring, but she later confirmed it was just a "promise ring."

Kylie and Tyga, 27, split in early April, seemingly only days before she starting hanging out with Travis.

In addition to Kim and Kylie, Khloe Kardashian is also allegedly pregnant right now. Khloe is reportedly expecting her first child, a baby boy, with boyfriend Tristan Thompson.

Meanwhile, Kim and husband Kanye West are celebrating Baby No. 3, whom they will welcome via surrogate. Like Kylie, Kim -- the mom of North, 4, and Saint, almost 2 -- is also expecting a daughter, Us reported.
