Tyga is getting some bling for his bday!

On Thursday, the rapper, who appeared to be carrying a Goyard man purse, hit up a Calabasas jeweler, Polacheck's, with some pals two days ahead of his 27th birthday. We know the "Rack City" performer is broke -- so we have a feeling that Kylie Jenner is paying for the tab on his birthday bling.

After the shopping excursion, the soon-to-be 27-year-old went home and was greeted by Kylie and his son King Cairo with a surprise birthday party, complete with sexy cupcakes. If you look closely you will see the cupcakes have King's photo on them, a photo of Kylie and Tyga, as well as reality star's boobs and ass. Classy!

Despite the graphic baked good, the videos of King surprising his dad are actually pretty damn cute -- and the whole crew seems really excited to wish the rapper a birthday. So that's sweet too.

What's not so cute is that in one of the Snap videos, Tyga laps up some of the frosting on the butt cupcake and says, “Gotta make it more real, gotta flatten it a little bit." Wow! Way to diss Kylie's curves. We guess if you're used to Blac Chyna's juicy booty -- Kylie's butt seems small, but that's still super harsh!
