(Cover) - EN Showbiz - Rosie Huntington felt "insecure" kissing Shia LaBeouf in the new Transformers movie because he's smaller than her.

Shia, who is reportedly 5ft 9in, is slightly smaller than his female co-star in Transformers: Dark of the Moon, even before she wears her high heels. The soaring model-turned-actress admits she felt uncomfortable during their kissing scene because of the height difference.

"At the beginning of the shooting it made me feel a bit insecure," she told the German edition of OK! magazine. "Especially in the kissing scenes the height difference was tricky. But Shia and I made fun of it. He said I would give hope to all the short men in America."

Despite coming under fire from movie critics in her big screen debut, the Victoria's Secret model would be keen to give up her modelling career for an acting one.

"I would love to do more movies! Acting feels so natural for me. I am so grateful that I got this opportunity and hopefully it's not my last movie. Of course I would miss modelling but maybe I could do a covershoot being an actress then!"

Rosie has no further film roles coming up as of yet. (C) Cover Media
