Hollywood actress Blake Lively uses "kung fu" to achieve her red carpet look, according to husband Ryan Reynolds.

The 27-year-old is impeccably dressed when promoting her movies but according to husband Reynolds, there is always lots of behind-the-scenes drama involved, reports femalefirst.co.uk.

"I see a totally destroyed closet, bedroom and kitchen...I don't even know how the shoes got in the freezer...There's kung fu involved. It's really intense," Reynolds quipped.

Meanwhile, Lively says that she got more "respect" when she had brown hair.

The blonde star, who darkened her locks to star in "The Green Lantern" in 2011, argued people treated her differently depending on the colour of her hair.

"I loved having brown hair. You feel different. I also felt different as a redhead. People treat you differently. Honestly, people respect you more with brown hair,` she said.

"They're a little goofier with you, a little zanier, when you have red hair."

The `Age of Adeline` actress also admitted she enjoyed the feeling of being pregnant, despite having to wear much bigger gowns to conceal her bump for the first few months.

"It was fun to be pregnant and to feel like I could own my womanhood," she said.
