Rapper Wiz Khalifa has finally staged his son's second birthday party almost a week after he accused estranged wife Amber Rose of sabotaging his original celebration by keeping their kid away.

Khalifa scheduled the bash for little Sebastian last weekend (21Feb15), and even took to Twitter on Saturday morning and wrote, "we bout to party super hard for my young prince."

He returned to the site hours later to share a number of sad images of the cake and presents that had been left untouched after his boy's no-show, adding, "Only thing missing was bash (Sebastian)."

He then took aim at Rose, without mentioning her by name, by lamenting, "ive (sic) never voiced my true unhappiness out of fear of the person I was with and what she would do to make me more unhappy of (if) anyone knew."

He managed to host the pirate-themed party at his home in Los Angeles on Thursday (26Feb15) - and this time Sebastian was the guest of honour, according to Tmz.com. Rose was a not present.
