Actor Bradley Cooper says he got "nervous" when he had to kiss a girl for the first time on the big screen at the age of 25. While recalling his earliest acting memories, the 40-year-old said the two things that have stayed with him are how anxious he was about kissing a female co-star for the first time and how awkward he felt when makeup artists wanted to blow dry his hair, reports pagesix.com. `My earliest screen test was for 'All My Children' or 'One Life To Live' or whatever they called Kelly Ripa's soap opera. Who knows what they tried to turn me into? I remember most they kept blow-drying my hair. I was maybe 25. My action was kissing a girl. Oh, I was so nervous,` Cooper said. The `American Sniper` star has locked lips with several famous beauties for entertainment purposes since his career took off, including Jennifer Lawrence in `Serena` and Amy Adams in `American Hustle` and he even kissed 93-year-old Betty White for a comedy skit on TV show `Saturday Night Live`. He has also done his fair share of kissing in real life and was earlier spotted smooching with his new girlfriend model Irina Shayk, in both London and New York City.
