Actress Ayda Field

Robbie Williams is reportedly enjoying a new romance with an American actress.The 'Angels' singer is said to be smitten with Ayda Field after secretly dating her for almost two months. Friends claim the couple, who met at a Los Angeles party, have become inseparable and have fallen for one another in a big way.One pal told Britain's Daily Mirror newspaper: "He hasn't been this into a girl for a long time and they're doing all the things couples do, like going to the cinema and watching DVDs at Robbie's house. He's smitten and the feeling's mutual."Unlucky-in-love Robbie was also impressed with Ayda - who has appeared in hit US TV shows 'Will and Grace' and 'Days Of Our Lives' - because she didn't reveal details of their budding romance after their first few dates.The 33-year-old singer recently hit out at the Hollywood dating scene,branding it "f***ing stupid" in an emotionally-charged rant on his website. He wrote: "There are a few dating rules people adhere to out here in Hollywood. And they're all f***ing stupid. Don't call until the next day.Then don't get back to him for at least two days, etc."It's all rubbish. If any of these rules are applied to me, I respond in kind by never speaking to them again."
