Do you think jungle-bootied GF Jessica Biel knows that her man has been trying to bring SexyBack with his longtime love Britney Spears? Well, not really, but the singer recently left two voicemail messages for Brit offering support in the wake of her baby sister’s pregnancy annoucment.

A Star Magazine insider claims J.T left Britster a pair of messages stating:

“It’s a new year and a perfect opportunity to make things right.”

Britney hasn’t returned his calls.

“She’s ignoring him,” says the source. “She’s not listening to anybody.”
