Because she's not seeking attention or anything...

On Tuesday Kylie Jenner posted a rather sexy Snapchat video of herself wearing a black corset, and it looks like the 18-year-old reality TV starlet is back to waist training -- and in no mood to wear a bra. Hello nipples! Seeing as she just broke up with Tyga and is back on the dating scene, it seems like she's doing her best to show the rapper what he's missing out on...

Kylie has been hanging out with rapper PartyNextDoor, and a source told Us Weekly that the two are "definitely dating." For his part, Tyga has been seen with busty British model Demi Rose Mawby, 21, and earlier this month the rapper was photographed with Love & Hip Hop: Atlanta star Karlie Redd. Still, Tyga insists he's not attached. "Single. Focused. Blessed. Living Life," he tweeted on Sunday.

So...is Kylie doing this for her new boo or is this just to make Tyga jealous?
