Kendall Jenner listens to her brother-in-law Kanye West's music when she works out.
The 19-year-old model loves to play tracks by the 'Bound 2' hitmaker - who is married to Kendall's step-sister Kim Kardashian West - when she is exercising or in the gym.
Sharing her workout playlist with Vogue magazine, she included Kanye's tracks 'All Day' and 'Mercy'. Completing the top five was Big Sean's 'I Don't F**k With You', Drake's '0 To 100' and A$AP Ferg's 'Work'.
Meanwhile, the 'Keeping Up With The Kardashians' star previously admitted she drinks lots of detox tea in the run up to fashion shows to keep her good physique.
She said: "I usually start my day off with a cup of detox tea. I have like 12 cups a day ...
"I like running. I've been trying to get back into it."
Despite enjoying eating right and exercising, Kendall believes the best beauty tip is to get lots of sleep.
She added: "My beauty secret is just getting a good amount of sleep. I feel like I at least need about seven hours, eight hours of sleep to function."
The raven-haired beauty works alongside celebrity trainer Gunnar Peterson to get into tip top shape.
She said: "I do whatever he tells me to do. Some cardio, some muscle-building to tone myself up.
"I'll run to a gym and get on the treadmill; I [also] do a lot of ab work and planking."
Kanye's issue with Kim's trainer
Kanye West threatened to replace his wife Kim Kardashian West's personal trainer when she insisted she "couldn't imagine" the reality star 15lbs lighter.
The 37-year-old rapper was disappointed that his wife's keep fit mentor wasn't overjoyed with the idea of the raven-haired beauty shedding more than a stone in weight, so the 'Power' hitmaker suggested replacing the exercise coach with someone else.
Speaking to her sister Khloe Kardashian on last night's episode of 'Keeping Up with the Kardashians', Kim said: "Do you want to die? Kanye literally went crazy on the trainer today.
"She [the trainer] was like, 'No way, I can't imagine you 15lbs lighter.'
"And Kanye's like, 'Wait a minute, you are the trainer and you're telling me you can't imagine her 15 pounds lighter?'
"So [Kanye said] we need to get another trainer then, because if I tell you that she needs to lose weight in between her toe[s] you are going to figure out a f****ing toe weight."
The sisters also discussed their step-father Bruce Jenner and his recent lavish spending after he splashed out more than $30,000 upgrading his quad bike.
Bruce - who is transitioning into a woman - admitted he was enjoying having some financial freedom after splitting from the siblings' mother Kris Jenner after 24 years of marriage.
He said: "For all those years I'd have to ask permission to buy a little screw for my helicopter.
"I didn't have to ask permission ... and that's a very good feeling."
But the sisters expressed their concern at the former Olympian's big spending.
Kim said: "Last time he was on his own he was in debt."
Kris Jenner eyes 'baby' Bieber for clan
Kris Jenner thinks Justin Bieber is the "best babysitter in the world."
The 'Keeping Up With the Kardashians' star, 59, took to her Instagram account yesterday to praise the 'Baby' hitmaker, 21, on the way he cared for her five-year-old grandson Mason - whose parents are Kourtney Kardashian and Scott Disick - while they were splashing about in the pool.
Alongside a photograph of Mason jumping on Justin's shoulders while playing in the water, she wrote: "#Mason & @JustinBieber family pool day!!!#bestbabysitterintheworld (sic)."
And Kris wasn't the only one who enjoyed watching her grandson hang out with the pop star as Justin also shared the picture online and referred to Mason as a "cool fan."
Meanwhile, it's been a difficult few weeks for the 'Boyfriend' singer as he's recently been slapped with a lawsuit filed by his ex-neighbour Jeff Schwartz, who has claimed he and his wife have been left with "emotional distress" following allegations Justin and his friends threw eggs at his house last year.
Justin pleaded no contest to vandalism and was given probation after the incident but Jeff has demanded more because he believes his payout of $80,000 for repairs was not enough.
Over the past two years Justin has hit the headlines for his shocking behaviour, which has resulted in him being arrested a number of times, but it seems the hunk is trying to turn over a new leaf after he apologised to his fans during his roasting on Comedy Central earlier this month.
He said: "I lost some of my best qualities. I'm looking forward to being someone to be proud of. Someone close to me once said how you rise from a fall is how you are truly defined as a man."
