Britney Spears has targeted her husband Kevin’s album release party at the end of this month to make her triumphant return as the svelte, sexy young starlet we once knew — and a source close to the family tells TMZ that she’s enlisted a small army of nannies, trainers, and nutritionists to put her through her paces to make sure she’s looking her best.

According to the source, Brit has hired a nanny for each of her sons, and is constantly in the gym “for hours at a time,” working out feverishly to shed all the extra poundage she put on while having two babies in 13 months — and indulging her penchant for Taco Bell gleefully and often along the way. “She really wants to make a huge splash at Kevin’s release party,” says our source, “and she totally wants to outshine Kevin and announce to the world that she’s back.”
