The duo were all smiles as they posed together for photographers, with Cooper looking sharp and dapper in a black and white suit (sans tie), while his ladylove looked glamorous in an elegant red gown, reported E!Online.
Their red carpet appearance is just further proof of the love between these two.
Cooper recently made fans swoon when he could not keep his eyes off of his supermodel girlfriend as she strutted the catwalk at Givenchy's Paris Fashion Week season debut.
