Oscar winners Julia Roberts and Nicole Kidman are Hollywood’s two highest-paid actresses, commanding $20 million and $17 million per film respectively, the Hollywood Reporter said Wednesday.

Even though “Pretty Woman” siren Roberts, 38, is making fewer movies and spending more time with her young twins, she remains Hollywood’s most powerful female star in salary terms, the Reporter said.

“She’s still perceived as the highest-paid actress in Hollywood,” the industry publication said of the holder of first place on its list of the 10 best-paid movie actresses.

Kidman, also 38, was in second place, mustering $16-17 million per picture since she won the best actress Oscar for her role as Virginia Wolfe in 2003′s “The Hours.”

“This Oscar winner has built her reputation on taking risky roles and accepting smaller fees just for the chance to continue challenging herself — but that doesn’t mean she can’t command the big bucks when she wants to,” the Reporter said.

Kidman has risen to the top of Hollywood’s most powerful women since she won the Oscar, emerging from the shadow of ex-husband Tom Cruise who she married when she was an aspiring Australian starlet.

She reportedly earned $17.5 million for her role in this year’s thriller “The Interpreter,” and $16 million for next year’s sci-fi release “The Visiting.” Her next big role is as photographer Diane Arbus in “Fur.”

Flaxen-haired Reese Witherspoon, who won world fame for her role in “Legally Blonde,” is in third place, commanding $15 million per picture, according to the Reporter.

“With a reputation for being a hard-working perfectionist and a tough producer, Witherspoon has cemented her place in Hollywood’s elite,” the publication said.

Witherspoon is currently on U.S. screens playing June Carter Cash in the Johnny Cash biopic “Walk the Line,” which is tipped as a possible Oscar nominee.

Next on the list is former child actress and “Charlie’s Angels” star Drew Barrymore who expects $15 million per film.

In fifth position is Oscar winner, Renee Zellweger, 36, star of such films as “Cold Mountain,” “Chicago” and “Bridget Jones’ Diary” who commands $10-15 million per film, although she did get paid a total of $21 million for the 2005 box office flop “Cinderella Man.”

Angelina Jolie was sixth, earning $10-15 million for roles in such films as the spy thriller “Mr and Mrs. Smith.”

Seventh on the list of female Hollywood powerhouses was “Charlie’s Angels” and “Shrek” star Cameron Diaz, who is paid $10-15 million per film, followed by Jodie Foster who can demand $10-12 million.

“Foster is somewhat of an anomaly. She chooses her movies carefully and is unafraid of taking time away from the spotlight,” the Reporter said.

South African Charlize Theron, 30, earns $10 million a film following her win of an Oscar for her role in 2003′s “Monster,” scoring her ninth place on the list.

Rounding off the list is former “Friends” star and Brad Pitt’s ex-wife Jennifer Aniston, 36 who is paid around $9 million per feature film.
