Kim Kardashian and Kanye West aren't the only color-coordinating couple in the family.

Following Kylie Jenner's 19th birthday party on Sunday night, Tyga and Kylie Jenner enjoyed a quiet dinner at Italian restaurant, Il Cielo, in Beverly Hills, California, which has been rated "one of the most romantic restaurants" in the area.

The two were a perfect match as they both stepped out in satin olive green outfits. The 26-year-old rapper's jacket perfectly complimented Kylie's lingerie-style dress, and the Keeping Up With the Kardashians star loved her look so much that she Instagrammed the style from all angles, and posted several snaps.

Kylie was again spotted wearing a diamond oval ring on that finger, though she and Tyga have insisted that they're not engaged. While the two showed some slight PDA as they left the restaurant holding hands, they were quite affectionate during Kylie's birthday party.

The youngest Jenner sister shared a photo on Snapchat of her touching tongues with Tyga, giving it the caption: "My bestie."
