Pop superstar Jennifer Lopez has vowed to shed her her excess baby fat like “normal” moms -– through exercise.Lopez — who gave birth to twins Max and Emme in February — has reintroduced a fitness regime, working out three times a week with celebrity personal trainer Gunnar Peterson. Her program now includes 20-30 minute walks with sets of push-ups and lunges.

The ‘Jenny From The Block’ hitmaker, sporting a string two-piece, was spotted getting to grips with her new exercise regime last week — by taking a dip in the sea from her multi-million dollar yacht.

The 38-year-old music diva was also snapped nipping out with husband Marc Anthony in a designer gown and exquisite expensive jewelry, according to Britain’s Daily Star newspaper.
