Inside Kylie Jenner and Travis Scott's Date Night in Los Angeles

Kylie Jenner and Travis Scott snuck away for a little one-on-one time.

The 20-year-old Life of Kylie star and the rapper enjoyed a night out together at an NBA Awards after-party at Poppy nightclub in West Hollywood on Monday night.

“Kylie and Travis arrived together, hand in hand around midnight through a private entrance," an eyewitness exclusively tells ET. “They couldn’t have looked [happier]!" According to the eyewitness, Scott performed at the after-party and sang his hits "Goosebumps" and "Butterfly Effect." They left the hotspot around 1:30 a.m. to get home to their baby girl, Stormi.

Jenner was all smiles as she left the club wearing a white off-the-shoulder cropped blouse and skin-tight leather pants with red stitching and sexy cutouts.

Jenner is frequently spotted in the sporty attire, she recently showed off her post-baby body in a stylish sports bra, leggings and clear heels.
