The Keeping Up With the Kardashians star and her hubby-to-be stepped out in NYC Saturday, holding hands and smiling as they headed to lunch, with Kim flashing her massive engagement ring as they made their way in.
For their romantic outing, the E! star rocked a long tan Celine coat, Celine cream dress and tan Tom Ford strappy stilettos, while the "New Slaves" hip hop mogul sported an infiniti scarf, black sweater olive-hued coat and black leather pants.
Before they stepped out, Kim showed off a photo of herself on Instagram striking a pose with her glam squad, along with the caption, "OG NYC glam crew! @makeupbymario @michaelsilvahair."
Today also marked the birthday of her late father Robert Kardashian, whom she paid tribute to in a sweet post on Instagram.
"Happy Birthday dad! Can't believe you would have been 70 today! Bet you're up there eating tons of Ralph's cake! Miss you & love you!," Kim wrote, posting a shot of herself posing with her dad when she was a baby.
Khloé, Kourtney and Rob Kardashian Jr. also posted touching tributes to their father on Instagram Saturday, with Khloé writing, "Happy birthday daddy! Forever missed. Forever loved! Forever my guardian angel!," alongside a shot of herself as a child cuddling up with her dad.
"Happy Birthday Daddy! We would have had a big party tonight! I wish I could touch your face," Kourtney wrote. "My [angel emoticon]."
"Missing You will be forever but forever Thankful. Happy Bday Dad, Love You and Miss You every day!," Rob also chimed in.
