Wiz Khalifa chucked his feud with Amber Rose to the side for a moment as he threw a belated party for their son, who is actually being eyed by Kelly Clarkson for her daughter River Rose.

"Wiz threw the bash at his home in Silver Lake Thursday. It was almost a carbon copy of the party he tried hosting last weekend, when Amber and 2-year-old Sebastian were no-shows," TMZ reported.

Amber Rose didn't attend the party in light of their alleged running feud. Wiz Khalifa blasted his ex in his social media after she failed to drop Sebastian off during his birthday on the rapper's house for a party.

This time Wiz Khalifa used his custody time to "bring friends and family together to celebrate the BD."

Meanwhile, Kelly Clarkson quipped that when River Rose grows up, she wants her to marry Wiz Khalifa and Amber Rose's baby Sebastian.

"Have you seen Wiz Khalifa's little boy? He was on the Grammys red carpet and I want River to marry him - it'd be so cute," she joked per Mirror.

She also said that River Rose won't be hanging around with North West, the daughter of Kanye West and Kim Kardashian.

"I don't think my kid would be talented enough to hang out with Kanye's kids. Apparently not any people are... I live in Tennessee and unless they're country stars, I don't see celebrities," she said.

In a previous report, Wiz Khalifa filed custody of Sebastian claiming that Amber Rose is not the best role model for him.

A report from TMZ said that among the complaints in the Wiz Khalifa custody claim include Amber Rose staying out all night as she leaves behind their son in the care of relatives or staff; the family dog licking Sebastian's face after eating its own poo; and Amber not paying too much attention to their son.
