Wiz Khalifa Threw The Saddest Birthday Party Ever For His Son Bash

Wiz also denies that he ever cheated on Amber Rose.

Amber Rose got into a war of words with both Kanye West and Khloe Kardashian last week, but her latest battle looks like it's even more personal: With her estranged husband, Wiz Khalifa.

The former couple's son, Sebastian, turned 2-years-old over the weekend, and Wiz was ready to celebrate with a party any toddler would love, full of gifts and cake.

But apparently Amber never dropped Bash off at the party -- the "only thing missing was bash," he wrote -- which turned Mister Cap from an excited dad to a sad one. After talking about his search for happiness, the rapper admitted, "i just need some help."

He also touched on his breakup with Amber, saying that he never cheated on her, a response to allegations she made shortly after their split became public.

Of course, we don't know Amber's side of what happened -- she did post a video celebrating with Bash -- but it's pretty clear that things didn't shake out the way Wiz had hoped for his son's big day.
