Expensive ride: Scott Disick takes a mystery woman for a spin round Los Angeles in his Rolls Royce convertible

With his convertible Rolls Royce and thirty year old attire, it's fair to say Scott Disick is a throwback from the 1980s.

Not that his female companion seemed to mind as he took her for a spin around Los Angeles yesterday.

The boyfriend of reality TV star Kourtney Kardashian looked every inch the Eighties yuppie as he and the mystery woman went for lunch in Beverly Hills.

Disick, 27, was snapped enjoying the unseasonal Los Angeles weather as he and his friend soaked up the sun in his car.

They were also spotted leaving a restaurant and took the opportunity to light up a cigarette as they made their way back to the car.

But it was Disick's unusual attire that really stood out, and he wouldn't have looked out of place in the Eighties with his high v-necked cream jumper, light blue jeans and brown loafers.

Disick is known for his yuppie dress sense and is often seen paying tribute to the decade that fashion forgot.

He is very fond of his suits with braces and wearing loafers without socks, resembling Christian Bale's character in American Psycho.

Disick has been dating Kourtney for the past four years and have a one-year-old son Mason Dash together.

They have had a turbulent relationship and he's known for his temper tantrums and violent outbursts which were made public on an episode of Keeping Up With The Kardashians in which he punched a mirror during an argument.

Kourtney took her family's advice and took a break from Scott after he became violent but after receiving therapy for his issues Scott appears to be a changed man and the Kardashian clan have clearly welcomed him back.

Even his mother-in-law Kris, who had vowed: 'I hate him, I hate him!' was been spotted at his side.

Scott and Kourtney also spent most of their summer in New York filming their reality show and attempting to make a fresh start in their relationship.

Yesterday, Kourtney and her sisters Khloe and Kim jetted back into Los Angeles from New York where they had been promoting their new autobiography Kardashian Konfidential.

The sisters' book details their lives so far and their rise to fame, and is just one of many projects the Kardashians are involved in.

One of those projects recently was stopped - the sisters have backed out of a credit card deal after it was blasted over 'outrageous' fees, according to U.S reports.

The card is being investigated by Connecticut Attorney General Richard Blumenthal, who claims it appeals to 'financially unsophisticated young adults'.

Now the Kardashians have issued a termination notice and returned their fees, the New York Post reports.

The family's lawyer, Dennis A. Roach, wrote in the notice that the sisters are 'honest, ethical and fun-loving individuals who are kind and caring to others... the negative spotlight turned on the Kardashians threatens everything for which they have worked.'

Aside from work, the Kardashian sisters are famous for their love of style and fashion.

While Khloe was showing off her curves, Kourtney stepped out with a bizarre Elvis-inspired quiff.

The sisters are open about their competitive sibling rivalry, and it looks as if Kourtney is not above experimenting with her hair to steal some attention from Khloe and Kim.
