(Cover) - EN Showbiz - Kristen Stewart says that she is finally embracing her femininity.

The 21-year-old Twilight star has had a very tomboy style since her fame rocketed in the popular movies.

But the actress has told British GQ in their November issue that her style is about to change.

Kristen graces the cover in a black retro bikini with perfect hair and makeup and looks the best she ever has.

Her dark hair was styled in Old Hollywood waves and she sported bright red lipstick while laying on a sun lounger by a pool.

The sexy transformation has led Kristen to declare she is ready to grown into her womanhood.

"I looked like a boy for a long time," she told the publication. "Now I feel like a woman."

Kristen will also show off her curves during honeymoon scenes in the second installment of Breaking Dawn.

She and her co-star and real life beau Robert Pattinson filmed beach scenes in St. Thomas where she donned a bathing suit.

The Twilight Saga: Breaking Dawn - Part 2 is out next summer. (C) Cover Media
