Kanye collaborated with sister-in-law Kylie's ex for 'Wash Us In The Blood'.

Kanye West has joined forces with Kylie Jenner's ex Travis Scott for a new track.

On June 30, Kanye himself dropped the music video for Wash Us In The Blood, which features Travis Scott's talents as well as Kanye's own.

The track will form part of Kanye's upcoming album God's Country and was mixed by rap icon Dr Dre.

Kanye is married to one of Kylie's big sisters, Kim Kardashian-West, with whom he shares four kids. Travis, meanwhile, has one-year-old daughter Stormi with ex Kylie.

The pair went their separate ways late last year but vowed to co-parent Stormi, and since then they've maintained a close bond.

Rumours have been swirling that the two are headed for a romantic reunion after Travis headed to Kylie's pad for the lockdown amid the coronavirus pandemic.

They seem to be on great terms, with Travis reportedly whipping up a lavish Mother's Day feast for Kylie, while the doting mum was forced to admit that Stormi is a "daddy's girl."

Meanwhile, Kanye and Kim are celebrating her joining the billionaires' club after she flogged a 20% stake in makeup brand KKW for $200 million.

Kanye is already a billionaire but isn't letting the title slow his climbing of the ladder.

He recently struck a deal with high street retailer Gap in a collaboration between the store and his fashion brand Yeezy.

The move saw the popular store's shares leap by a staggering 20%.
