★More ABS NEWS - Entertainment Video►► / @tinancoltd Tommy Lee and Charlotte McKinney were among the stars ready to build a better burger on Saturday.Both were among the celebrities in attendance at the Off the Menu and Postmates Best Burger Challenge in the Wallis Annenberg Center in Beverly Hills, California, where burger makers teamed up with the stars on hand to create the tastiest secret menu fare.McKinney, a 24-year-old model-actress, looked amazing at the proceedings in a sheer white top over a pair of barely-there black leather shorts. She added even more inches to her statuesque frame with a pair of bright white leather heels, with ankle straps tied into massive bows. The Baywatch beauty had her blonde locks pulled back and in a bun - fitting for the day's proceedings - as she carried a black leather purse.While she took a more natural approach with her makeup, Charlotte swiped a pale pink shade across her lips to match a bit of blush on her cheeks. Lee, 55, and his fiance, Vine star Brittany Furlan, 31, posed at the event, where Tommy wore a grey T-shirt with black jeans and black high tops with straps. The Motley Crue drummer and his fiancee have been in the headlines over the past few months after he was punched in March by his 21-year-old son Brandon over remarks he made about Brandon's mom, Pamela Anderson.Furlan was clad in a white dress with horizontal pinstripes, a yellow jacket and a black fiddler cap with heeled black boots. The social media stunner had a few dogs on leashes as she posed with the tall rock star.Also snapped at the event was Pretty Little Liars star Shay Mitchell, 31, who wore a black top tied above the waist with torn jeans with a mid-ankle rise and snakeskin heels.The dark-haired beauty accessorized with sunglasses and earrings at the culinary event.According to Eventbrite, companies at the event on Saturday included Badmaash, Burgerlords, Button Mash, Cassell’s Hamburgers, Grill Em All, Malibu Burger Co., Plan Check, Top Round and Wolf.
