Kylie Jenner enjoys cheerful outing with Tyga... hours before learning former brother-in-law Lamar Odom is in a coma after collapsing at brothel

Kylie Jenner was pictured on a cheerful outing with boyfriend Tyga on Tuesday, just two hours before learning her former brother-in-law Lamar Odom is fighting for his life.

The 18-year-old abruptly ended a live stream on her website that evening, after the former NBA star was found unconscious at a Nevada brothel.

Before Kylie took part in the brief live stream, she was seen in Los Angeles, picking up the $320,000 Ferrari Tyga bought her for her birthday in August.

The reality star seemed in good spirits as she and her 25-year-old rapper boyfriend did some shopping at Westfield during their outing, and then collected the car after a paint job.

Kylie was wearing an outfit that looked as though it had come straight out of her sister Kim Kardashian's wardrobe – a tiny brown bra-style crop top with a matching pencil skirt featuring a generous slit up one thigh.

The teen showed off her cleavage and legs in the ensemble, which she paired with grey suede pumps, dark lipstick and smoky eye make-up.

The youngest member of the Kardashian/Jenner clan then headed home for her live stream, which she ended suddenly after hearing the news about Lamar.

At 6:08pm PST, Kylie tweeted that she would be starting a live stream 10 minutes later.

However she then cut it short, and wrote to fans 11 minutes later: ‘Had to end my live stream. I love you guys.’

Following news of Lamar’s collapse, his ex-wife Khloe rushed to be by his side at Sunrise Hospital in Las Vegas.

She was joined by sister Kim Kardashian West and mother Kris Jenner, who was pictured looking distraught outside the hospital in the early hours of Wednesday morning.

Kim and Kris were spotted arriving back to the hospital later on Wednesday morning, with Khloe presumably having stayed at Lamar's bedside throughout the night.

Kourtney was seen later in the day boarding a private jet to fly to Las Vegas and join her family. 

Kendall Jenner, 19, arrived a short while afterwards, having flown overnight from Shanghai, where she had been attending fashion week. She tweeted on Wednesday morning: ‘Please don’t go.’

Khloe was married to Lamar for four years before filing for divorce in December 2013, amid claims of drug abuse and infidelity.

The divorce has not been finalised, a Los Angeles Superior Court rep told Us Weekly on Wednesday. 

Lamar is fighting for his life after an alleged 'crack-cocaine and opiate-fueled' weekend, and sources have claimed that his collapse may have been sparked by his negative portrayal on Keeping Up With The Kardashians. 

Doctors are currently treating Odom's case as a non-suicidal drug-overdose, according to a source at the hospital who spoke with E! News who says that doctors found 'virtually every drug imaginable' in Odom's system.

TMZ claims that an MRI revealed Odom suffered multiple strokes, and it's unclear if he has brain damage as a result.

The website added that the 35-year-old is on a three to five hour dialysis for kidney failure, and claims four of Lamar's organs are failing. TMZ alleges doctors are saying he has a 50/50 chance of surviving.

Two prostitutes found the former NBA star unconscious and foaming at the mouth on Tuesday afternoon in a VIP house attached to Dennis Hof's Love Ranch, a legal brothel in Pahrump, Nevada.

'There was some blood coming out of him. The 911 operator asked them to turn him on his left side and of course he's a big guy, so it was a big challenge,' proprietor Dennis Hof told E! News.

'They did that and a lot of stuff started coming out of him. He started throwing up and they say it was a horrifying sight...Then the paramedics took over.'

Hof said Odom was in high spirits when he picked the athlete up at his LA gated community on Saturday, but says he became 'bummed' after receiving a phone call on Sunday.

Sources tell TMZ that the phone call was related to his portrayal on the reality show Keeping up with the Kardashians, and that after taking the call he became 'irate' and remained inconsolable up until he was found unconscious.

Odom was allegedly triggered by a repeat of Keeping Up With The Kardashians which aired on Sunday, in which Khloe told the cameras she was worried Lamar would ‘spiral’ out of control.

Khloe could be seen taking a call from Lamar after news broke of the drug-related death of his best friend Jamie Sangouthai, the best man at their wedding.

‘Lamar has suffered so much loss in his life - I’m always going to be there for Lamar especially when something as tragic as this happens,’ Khloe said. ‘I’m really on high alert for Lamar because anything I think will cause him to spiral and that’s really the last thing I want for him.' 

During the same episode, Kim criticised Khloe for acting ‘flirty’ while taking to Lamar on the phone. 

‘He hurt her so badly,’ Kim said, adding that Khloe was making it difficult for herself to move on. ‘For her to be flirting with him on the phone makes me sick to my stomach.’
