Chris Brown's Ex Karrueche Flashes Her Taut Tummy

She's partial to an ab-flashing outfit. And Karrueche Tran opted for a familiar look as she bared her taut tummy in a cropped t-shirt and form-fitting leggings while out and about in Los Angeles on Monday. Hitting the streets of West Hollywood for some daytime errands, the 27-year-old model and actress cut a casual figure as she displayed her toned frame and washboard abs in skintight sportswear.
