It all comes on the heels of reports that surfaced during the showdown in Atlanta between the New England Patriots and Los Angeles Rams when Jenner's sister posted a snap rocking a huge rock on her left hand.
Explaining her lavish outburst, Kylie shared a photo of herself holding the birthday girl to Instagram and simply put: 'I had to go all out for my baby'.
Throughout their dinner, Jenner was seen cuddling up to Simmons and kissing his face, according to TMZ, which published a photo of Jenner wrapping her arm around Simmons. "I think she was like, 'We are like looking good and really into each other then maybe baby number two is going to happen... they're practicing", she said. "Is that what you call it? I'm not engaged. There's nothing long-term or serious like that in my life", she told Harper's Bazaar in 2017. We've known this since the model has been sitting courtside at Ben's basketball games for a while now (and a few times she's been next to his mom) but she's never fully discussed Ben until now. "She's really clever. I don't think she's pregnant".
Turning up the heat, Jenner replied with a racing vehicle emoji - seemingly implying she's on the way. But if he did, she hasn't told the family yet.
