Big Sean And Ariana Grande Officially Dating??

We all know that Ke$ha and Big Sean (who are both PSR artists) are married and expecting their first child right? But for some reason, Big Sean is now linked to Ariana Grande (Who is a former PSR artist). They have been in 3 songs together, including Ari's recent single "Problem" which also features Iggy. Normally we would say "That's a rumor, whatever" but Ari confirmed it this morning and posted "Me and Big Sean are in fact dating, I love him so much" HUH???????? So why isn't Ke$ha responding? Well some say  that she knows about it, and that Big Sean has been her friend for years and now they are taking it to the next level regardless of Ke$ha,  and that she is the reason why Ke$ha and Big Sean have so many arguments, but still she isn't doing anything about it. (Really Ke$ha, you're gonna let your husband fuck another girl and not say anything at all???) Sorry I had to say that. Big Sean and Ari are literally EVERYWHERE together, videos, songs, movies, dinner, charity events you name it, they are there with each other hand in hand. Sources say they were spotted kissing at the movies where they went last week with each other. Some sources say they have been knowing each other for years and  they are just super super close that's all. Here's how we feel. We get that some women have male besties (although I would NEVER let my wife have a male friend, but that's just me) and maybe they can hang out sometimes, but when you start going on romantic dates like movies, dinners, waterfalls like they have been doing lately, that's WAY more then a friendship. I would say the most a male and female friend should do is hit jack in the box take out, chill for a minute and call it a day, Ari and Big Sean are doing WAY more then that, so it seems that its alot more then friends. Even in their new video "Best Mistake" they are all hugged up with each other seemingly kissing, tell me what the hell kind of friends is that? Sources say that they are not bothered by the fact that she is 21 and he is about to be 27, age ain't nothing but a number right? Have you seen those two recently? Damn,  Ari is Big Sean's shadow. I just feel bad for Ke$ha though, but like I said last time, you can do SOOOOOOO much better Ke$h, What do you guys think about this?
