Sporty, arty and business savvy. A ranking of the world's top 20 most intriguing billionaire heiresses by Web site Forbes.com shows daughters of the rich aren't all just socialites and can be hard workers.

While hotel heiress Paris Hilton hit the headlines for spending time in jail and making a sex video with a boyfriend, Forbes.com said the women on its list were "proving themselves every bit as tenacious and ambitious as their namesakes."

In top spot on the list is Vanisha Mittal Bhatia of India, who has a master’s degree in South Asian studies and sits on the board of Mittal Steel, owned by her father Lakshmi Mittal, estimated by Forbes to be worth $51 billion.

"She's perhaps best known for the $60 million Parisian wedding her father threw her and 1,000 of their closest friends in 2004.” said the Web site (www.forbes.com).

The women on the list are all under 40 and ranked according to their father's or mother's most recent net worth on either Forbes' World's Billionaires list, the Forbes 400 list of the Richest Americans, or Forbes Asia's 40 Richest Indians.

Coming in at No. 2 is Delphine Arnault Gancia of France, daughter of Bernard Arnault who runs the Moet Hennessy Louis Vuitton (LVMH) luxury goods empire. Gancia is a former McKinsey consultant and the first woman to be named a director on the LVMH board, Forbes.com said.

Third is Marta Ortega Perez, youngest child of Spain's richest resident Amancio Ortega, worth an estimated $24 billion and chairman of Inditex, owner of the Zara clothing chain.

"Marta is being groomed to succeed her father, and she's learning the how-to's of retail by working the floor -- stocking shelves, assisting customers -- in some of the family's stores," Forbes.com said.

Georgina Bloomberg, daughter of New York City Mayor Michael Bloomberg -- majority owner of Bloomberg LP financial news and data company and estimated to be worth $11.5 billion -- comes in at No. 4. She is vying for a spot on the 2008 US.Olympic equestrian team.

Samantha Kluge takes No. 5. She is the "sometimes wild child" of communications mogul John Kluge, estimated to be worth $9.5 billion, and boasts 12 tattoos and two annulled marriages, Forbes.com said.

Josie Ho Chiu Yi, daughter of Stanley Ho, Macao’s casino mogul, stands at the eighth. She is an actress and singer.
