Britney Spears and Isaac Cohen are going strong!

Though Isaac Cohen has only been in Britney Spears's life for a month, but she's been in his for years. Cohen's high school girlfriend claims that he had a crush on Spears back when she first hit it big.

The woman, Jennifer Sypal, tells Us Weekly, "[Cohen] thought [Spears] was ho. He was into her music, too." Jennifer says that Isaac was so into Britney that he even called her Britney because they looked similar.

Luckily for Cohen, it seems his dream girl is equally taken with him. Last Friday she and some friends went to a store in Los Angeles called Trashy Lingerie and purchased a Valentine's Day-themed outfit, reports People magazine. Bridget Silvestri, a rep for the store, claims the outfit "was anything but trashy. It was classy and sophisticated and perfect for her…She said it was for someone special."

Isaac is sure to be the person Britney intends to share her new purchase with. They've been nearly inseparable lately. When asked by Us about Spears, Cohen said, "She's the ultimate sweetheart." He was reluctant to say whether their love was lasting, however, and replied, "I'm taking it one day at a time."
