The 24-year-old Keeping Up With The Kardashians star — who is currently pregnant with baby #2 — was caught wearing the blinding sparkler at an airport in Los Angeles on Tuesday.
Photographers quickly snapped the shots, showing Kylie getting out of her car and putting on her coat. The rock adorning her left ring finger was hard to miss.
Covering her growing baby bump in an oversized black sweater, the billionaire business mogul exited her black Rolls-Royce in sweats before slipping into her cream-colored puffer jacket.
Keeping it casual, Kylie chose comfort by sliding into a pair of Yeezys — showing she still supports her soon-to-be ex-brother-in-law Kanye West despite his ongoing divorce with Kim Kardashian.
She also made sure to accessorize with tons of jewelry, including gold earrings, but nothing could turn attention away from the diamond ring.
While her baby daddy was nowhere in sight, Kylie wasn't alone.
Showing mommy duties never stop, the Hulu reality star walked onto a private plane with her three-year-old daughter, Stormi Webster, on her hip. Juggling her toddler, her growing bump, and her bag, Kylie showed she's a pro when it comes to traveling with her child.
Kylie's engagement rumors come just hours after she flashed another ring full of diamonds given to her by Travis. Taking to her Instagram, the KUWTK star showed that Christmas came early this year thanks to her man!
Taking a photo of the stunning ring, Travis didn't think only one diamond was good enough for the mother of his two children. Wearing the band on her index finger, Kylie showcased a square diamond and another obscure-shaped sparkler.
The Highest In The Room rapper also made sure to get two rings — one for Kylie and the other for Stormi. "Daddy got us matching rings," Kylie captioned the photo.
In August, the couple revealed they were expecting their second child. Kylie gave birth to Stormi in February 2018. Kylie and Travis' relationship hasn't been perfect.
They called it quits in 2019 but made sure to focus on co-parenting. In April of this year, Kylie was spotted all over Travis in Miami for the rapper's 30th birthday, and they have been inseparable since.
