Adrien Brody and model girlfriend Lara Lieto share passionate kiss

They fell head over heels when meeting at the Cannes Film Festival back in 2013.And Adrien Brody's romance with Russian model Lara Lieto has seemingly gone from strength to strength as the pair shared a passionate kiss while out running errands in Beverly Hills, California, on Sunday.The couple looked very much in the throes of love as they indulged in a tender moment after fulfilling the rather menial task of purchasing pet food. Before the lovebirds drove off in the Hollywood actor's brand new Aston Martin, Adrien, 44, leaned in for a smooch, which was followed by a loving look from the 24-year-old.  Lara looked chic for the low-key outing in a black maxi dress, which boasted a flattering halter-neck fit and white stripes across the torso.She put a more casual spin on the ensemble by teaming it with comfortable trainers and left her long brunette tresses to fall around her face in a sleek style. Adrien matched Lara's dark colour palette in a simple grey T-shirt on the errand run.  While The Pianist star chooses to keep details of his long-time relationship with Lara under wraps, the pair are rarely spotted without one another, with the Russian beauty frequenting many a red carpet with her actor beau. Despite being one of Hollywood's biggest stars, and one of the youngest winners of an Academy Award aged 29, Adrien admitted last year that he has reduced his acting roles so that he can devote more time to working behind the camera.Explaining why he has chosen to scale back his output, he told The Hollywood Reporter: 'I’ve kind of pulled back a bit on the acting side because I've worked a lot the past year or so.'I've been focusing on a few things I'm producing. It’s an interesting time.' Fans of the Peaky Blinders actor will next see him feature as Charles V in the Emperor and alongside fellow Hollywood heavyweight Bruce Willis in The Bombing.
