What could this mean?

So my friend just put on fb that her and this guy nobody knew about are in a relationship.

Going through the comments none of her friends knew about him, but all of his did and they were saying how they are going to have a great life together and such and how they were happy to meet her, like they just got engaged

but someone posted a joke saying they had to breakup bc they are fans to the rival football team as a joke, and the guy said they worked that detail out….. what would that mean? I just been snooping and went down this rabbit hole

but what would be you alls opinions you think she got knocked up or something else like they got engaged? They also just met within two months bc she was with someone two months ago
