The Keeping Up With The Kardashians star's choice of clothing comes amid reports from the US that Khloe has 'split' with her boyfriend French Montana.
Although the couple have not commented on the claims, a source told People that the former couple are still talking and remain friends but Khloe had decided it "just wasn't working out" between them.
Khloe and French had been dating since April but despite living her life in the glare of the public, she rarely spoke about their relationship. In June, however, Khloe was pictured at her birthday party in New York with French and she also spoke about her man in a radio interview weeks later.
Addressing French's bad boy image, she said at the time: "People are gonna comment no matter what. If I dated the most clean-cut perfect guy, they're gonna comment.
"If I'm having fun and I like this kid, that's just the way it is. Why should anyone else care?"
Yesterday, Khloe didn't look in the best of moods as she arrived at the gym. Along with her 'B*TCH PLEASE' vest, the star was wearing leggings, bright pink trainers and a pink band tied in her hair.
This was the second day in a row that Khloe had headed for a workout, as she was also snapped at the gym on Wednesday.
Nothing like pounding the treadmill to make a girl feel better, eh Khlo!
