Bruno Mars, 31, andJamesCorden, 38, sure know how to get down! If you don’t believe us,just check out the Dec. 13 “Carpool Karaoke” during which Bruno and James totally crushed the singer’s greatest hits! But come on, did anyone doubt that Bruno would be anything short of amazingwhen it was announcedhe would be the next star on “Carpool Karaoke”? We didn’t, and he did not disappoint us!James started off the epic segment by thanking Bruno for helping him get to work byjoining him on his ride through Los Angeles. He then complimented him on his hats, saying “There isn’t a hat you can’t wear.” And Bruno admitted the reason he always wears hats is he doesn’t know what to do with his hair. Then the pair hilariously tried on different hats together, including a giant top hat and a bright blue wide-brimmed lady’s chapeau. And OMG did Bruno pull off both of them!Then James and Bruno jammed to “JailhouseRock” a cappella, after the singer showed the late night host he could strike Elvis Presley‘s signature lip pose. While they were singing “Versace On The Floor,” James hilariously noted that Bruno left out the part about needing to remove your spanx as well! “All that song teaches me is that you and I are very different in the bedroom,” he told Bruno. After Bruno told him that he usually requests some booze, water and wet wipes in his dressing room, they came up with a new song, “Wine & Wet Wipes,” singing the lyrics “pop the cork and wipe down” and “wipe my face put some liquor with it,” to the tune of “Uptown Funk.” Then, they switched over to theactual “Uptown Funk,” and the pair totally lost it singing along. By the end of the segment James was actually dressed up like Bruno!‘The Late Late Show’ With James Corden — PicsWe can’t get enough of “Carpool Karaoke,” and James continues to outdo himself with the stars he brings along on his rides. On Dec. 8, James brought on thelegendary songstressMadonna, 58, to help him get around the streets of NYC. She ended up showing him how to twerk in a car and dishing on her short-lived romance with the late Michael Jackson. She even confessed tokissing him! We never thought anything couldtop that, but then came Bruno!
