Toughing it out! Sofia Richie proves she has stamina as she dons heavy coat at Kanye's Yeezy show as other models faint

Sofia Richie's star continues to rise - fast.

The 18-year-old daughter of All Night Long singer Lionel Richie on Wednesday chalked up another milestone in her blossoming career, as she walked the runway at Kanye West's Yeezy Season 4 in New York in her debut for the rapper's fashion line.

In the outdoor fashion show - which began more than 90 minutes late at Franklin D. Roosevelt Four Freedoms Park, leading one model to faint in the heat - Richie braved the pounding East Coast heat.

She pranced out on a white runway set up amid grass, clad in a wintry green coat and thigh-high boots. 

It's another feather in the cap for the young beauty, whose budding relationship with Justin Bieber - the two were spotted traveling through international locales like Mexico and Japan over the summer - remains an interesting item to watch with the onset of fall. 

The teen, whose sister is fellow fashionista Nicole Richie, told photographers in Beverly Hills Friday she was 'uncomfortable' with chatter about the romance.

Cover up in a luxe spring shearling by Yeezy like Sophia

While some seasoned models fainted in the 80 degree sweltering heat of the Yeezy season 4 fashion show, Sophia Richie showed them all how to be a pro by walking in a citrusy colored shearling coat with a hood and thigh highs. Talk about pro move.

A black or dark-colored coat would have looked so wrong but this vividly colored coat really played well with the green grass and ultra bright sun. Think about the longer nights ahead and how this hue will work like a treat and feels so contemporary.

She sauntered away from the inquisitive pap as he peppered her dad with questions about it.

Lionel laughed off inquiries about whether they were dating, as the Dancing on the Ceiling singer told paps, 'I'm not going there - I have strict instructions not to go there.'

Bieber's devotion to Sofia in their newfound relationship even led the pop star to delete his Instagram account last month when commenters, some of them Selena Gomez loyalists, began taking jabs at her.

An annoyed Biebs warned fans, 'I'm gonna make my Instagram private if you guys don't stop the hate this is getting out of hand, if you guys are really fans you wouldn't be so mean to people that I like.'

When the trolling continued, the 22-year-old Canadian Baby singer pulled the cord on the social media account, which boasted more than 77 million followers. 

That led to a Twitter hashtag dubbed #JustinDeactivatedParty, as thousands rejoiced at driving him the format. While his account was eventually restored, Bieber chalked it up to an accident and remains silent on the site for now.
