Bradley Cooper was ''so nervous'' when he had to perform his first screen kiss.

The 40-year-old actor has recalled his earliest acting memories and 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 make-up artists wanted to blow dry his hair.

The 'Limitless' star told the New York Post newspaper:''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!''

The Hollywood hunk has come a long way from his first awkward screen smooch.

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 planted a smacker on 93-year-old Betty White for a comedy skit on 'Saturday Night Live'.

Bradley has also done his fair share of kissing in real life and was most recently spotted smooching with his new girlfriend, model Irina Shayk, in both London and New York City.
