I think it's still appropriate to give a birthday girl her birthday spankings at the age of 25, especially if that birthday girl is the stunning Rosie Huntington-Whiteley. The English model turned actress is the ripe, young age of 25-years old on April 18th. Rosie is known worldwide for her seductive spreads for Victoria's Secret. Her resume also includes appearances in various magazines like Maxim, GQ, Vogue, Complex, and Harper's Bazaar. Huntington-Whiteley topped Maxim's Hot 100 List and was named as FHM's 100 Sexiest Women in the World in 2011. And, of course, the ravishing model replaced the also alluring Megan Fox in the "Transformers" movie franchise. If you were planning on sending Rosie a birthday present, save yourself some cash because she's currently dating action movie star Jason Statham. However, that doesn't mean you can't gawk at the 50 hottest photos of Rosie Huntington-Whiteley.
