New York, Apr 24 : Chelsea Clinton is all set to welcome the bikini season, with a newly acquired fit and trim body.

According to sources, the former first daughter of United States has become a near-constant spin class fixture at the new SoHo outpost of Ride the Zone.

"It''s funny. She''s sweet as pie when she arrives, but the minute she gets on the bike, she''s suddenly really focused and intense," The New York Post quoted a source as saying.

And her slim figure clearly shows that all the hard work is paying off, because Chelsea "looks amazing."

Currently studying Health Policy and Management at Columbia University''s Mailman School of Public Health, Chelsea is dating longtime beau, Marc Mezvinsky. (ANI)
