Taylor Swift Gifts Concert Tickets to Amber Rose and Son, Sebastian

Amber Rose and her son with Wiz Khalifa are total Swifties -- and, as it turns out, Taylor Swift is a total ... Rosie? Ambie? Whatever ... point is, she hooked 'em up big time.

Amber surprised the hell out of her and Wiz's 5-year-old kid, Sebastian, with a gift set that was apparently sent straight from Taylor herself ... and it included tickets to her concert!

Seb's reaction is pretty damn cute -- like a scene straight out of a classic Christmas movie ... with lines such as "What is it?" ... "Really? For real?!" ... and "This is gonna be so exciting!"
