Fergie and Josh Duhamel have been more adorable than ever lately. A week after taking their son Axl, 2, to his first Dodgers game, the couple arrived at the Pandora Summer Crush concert in LA on Saturday looking like a picture-perfect family. They smiled wide for photographers before Fergie hit the stage to perform a very sexy rendition of her latest hit, "M.I.L.F. $." She donned the same jaw-dropping black latex get-up and seductive thigh-high boots that she wore to The Creative Coalition's Benefit Gala in Philadelphia in late July, proving yet again that she seems physically incapable of aging.
