It appears the Kardashian clan may have something ELSE to celebrate besides Kylie Jenner’s reported pregnancy! Kourtney Kardashian’s ex and baby daddy, Scott Disick, 34, appeared to be making an announcement of his own this weekend when he was snapped by paps sharing a smooch with Sofia Richie over a mysterious cake, which, interestingly enough, read, “Congratulations, Scott and Sophia [sic]!”

While we’re not entirely sure WHAT it means, the maybe-couple definitely had something up their sleeves, as a video from TMZ showed people clapping around them and waving sparklers as they embraced.

Instantly, the rumor mills began churning about what the fête implied for the pair, who have not publicly commented on their relationship or lack thereof as of late.

Disick has been linked to a number of young women this year, including actress Bella Thorne, who he was spotted “hanging out” with on multiple occasions, even after her emphatic denial that they were, in fact, dating.

In addition to Thorne, Richie has been popping up time and time again in the extended Kardashian family member’s inner circle. For months, the two have been entangled in plenty of “Are they or Aren’t they?” headlines.

Nicole Richie’s 19-year-old little sis took to Twitter back in May to say that she and Disick were “just homies,” but from there, her posts seemed to take a turn for the cryptic — and possibly romantic — with generalized statements on love, including “Love is a crazy thing,” and “Fall in love with someone who doesn’t make you think love is hard.”

From the looks of things, the pair has progressed far beyond “homies” now, though we remain in the dark over that exclamatory dessert, with fan guesses ranging from a mere restaurant prank, to an official couple announcement, an impending baby, and even engagement news.

There doesn’t appear to be any hard feelings with the rest of the fam, however — Kylie herself was seen snuggling up to the model for Jeremy Scott’s show back in February.

Congratulations to the happy… couple?
