Amber Rose and Beyoncé want kids to wed

Amber Rose hopes her son will marry Beyoncé Knowles' daughter.

The 29-year-old model has Sebastian - nicknamed Bash - with rapper husband Wiz Khalifa.

Her little one was born in February, almost exactly a year after her famous pal Beyoncé gave birth to Blue Ivy, her first child with Jay Z.

Amber wants the two celebrity kids to end up together, despite the slight age difference.

"My sweetheart @beyonce and I chopped it up about Bash & Blue Ivy they're gonna get married 1 day.... Bash likes older women Lol (sic)," she cheekily posted on Instagram.

Amber attached a picture of herself with the singer, pouting at the camera in a black and purple vest top.

Beyoncé smiles next to her, looking relaxed in a patterned T-shirt, denim shorts and a bold necklace.

It seems there is a lot of baby joy in Amber and Wiz's circle of family and friends right now.

The pair took to Twitter to pay tribute to Wiz's uncle, who recently welcomed a second child.

"Congrats to my Uncle @Motormane & @krysnicole on their Lil Bundle of beautiful joy!!!! God Bless," Amber wrote.

"Yo my uncle @Motormane juss welcomed his second child into the world! Cant wait to get my hands on the little guy #blessed #newcousin (sic)," Wiz added.

Amber and Wiz recently celebrated their marriage with a big ceremony for family and friends.

The couple tied the knot in a small ceremony on July 8, and had a party in August.
