The two were together at the "Studio 54" themed birthday party held by Markus Molinari and John Terzian in L.A. on Saturday, when fans noticed the rock on her finger, sparking engagement rumours immediately.
A source previously told Hollywood Life that, "It's starting to get really serious now between Kendall and Rakim [Mayers]. They both wanted to take it slow and keep it casual at the beginning, which makes sense considering their age and crazy hectic work schedule. They didn't want to jump straight into a relationship, and they also loved keeping everyone guessing."
It's pretty obvious how ~together~ they are, despite rumours swirling last week that A$AP was cheating on the model already...
The source continued, saying that, "They didn't want to start out under the media glare, so they vowed to take it easy, and to limit the amount of times they were seen in public together, in addition to steering clear of any joint red carpet appearances.
"They started realising they really have something special, a very strong connection and bond, and they're now both fully committed to being in a monogamous and serious relationship. They've started upping the amount of time they're seen out with each other, and they will be making red carpet appearances together in the future."
So, look... since their relationship is so fresh in the media, we aren't 100% sold on the fact that they would jump to marriage just yet. Maybe the ring is just a gift?
Why she's wearing it on THAT finger is ~suspicious~ but hey, girl does like to keep people guessing!
