Travis Scott is just hours away from performing his first major solo show since Astroworld … and he’s got some important people there to support him as he takes the stage.

Kylie Jenner and the couple’s daughter, Stormi, have been in London with TS all week — doing some shopping, dining and spending some time together. The show is a big deal for Travis, so you gotta imagine he’s enjoyed some family time leading up to it.

Unclear if Kylie and Travis’ 6-month-old son made the trip, but he’s old enough to fly … so it’s possible he’s just been staying with nannies while mom, dad and big sister hit the town.

Travis is scheduled to perform two sold-out shows at London’s O2 Arena Saturday and Sunday night … a venue that holds about 20,000 people. A source close to Travis tells us he’s, “excited to deliver for his fans in London by being back, thriving on stage.”

We’ve seen Travis pop up at nightclubs and perform a song or two during other artists’ sets, but the O2 shows will mark his first solo shows since November at Astroworld.

Travis has taken a lot of heat for the 10 deaths that occurred at the festival, and is fighting a mountain of litigation … but has seemingly been greeted with open arms by music fans and those hoping to score some of his merch and collabs he’s released since the tragedy.
