Actress Drew Barrymore says she wants to expand her beauty line to be sold across the world in the likes of Australia, Britain and China.

The "Miss you already" star's own make-up range, Flower Beauty, has been available exclusively in Walmart for five years, but she now has plans to branch out to countries across the world, reports femalefirst.co.uk.

Despite opening her range to a wider market, the mother-of-two -- who has daughters, Olive, three, and 20-month-old Frankie with husband Will Kopelman -- doesn't want to "hike up (her) prices."

The actress declined to disclose Flower Beauty's sales, but pointed to the fact that it's sold in nearly all of Walmart's 4,000 stores.

"They would drop us like a hot potato if we didn't deliver," she was quoted as saying by the New York Post newspaper.

While Barrymore said she is "proud" to work with Walmart, she conceded that "I get this look when I say I'm exclusive to Walmart, and yeah, I get it."

Meanwhile, Barrymore previously revealed she believes her beauty range "empowers" women.
