Jesse James says he is "truly very sorry for the grief" he has caused wife Sandra Bullock and his three children because of his "poor judgment."

The apology, which was issued yesterday in a statement to People magazine, comes in the wake of tabloid and entertainment magazine reports that James, 40, was romantically involved with another woman — something James neither confirms nor denies in his carefully worded mea culpa.

The former host of TLC's "Monster Garage" calls the "vast majority" of allegations against him "untrue and unfounded." But he took full responsibility for the unnamed actions, stating: "there is only one person to blame for this whole situation, and that is me. ... I deserve everything bad that is coming my way."

Eyebrows were raised Wednesday after Bullock, 45, canceled an appearance at Tuesday's London premiere of "The Blind Side," citing "unforeseen personal reasons."

PRODUCER SUES LADY GAGA FOR $30.5M

NEW YORK — A songwriter and music producer who says he helped launch pop star Lady Gaga says she squeezed him out of her lucrative career after he co-wrote some of her songs, came up with her stage name and helped get her record deal.

Rob Fusari filed a $30.5 million lawsuit against the Grammy Award-winning performer, saying his protege and former girlfriend ditched him as her career soared.

The lawsuit, filed Wednesday, says Fusari has been denied a 20 percent share of song royalties, 15 percent of merchandising revenue and other money he's owed from their personal and business relationship, which began in March 2006 but had soured by 2008.

POLANSKI LAWYERS ASK FOR INVESTIGATION

LOS ANGELES — Roman Polanski's attorneys filed an appeal yesterday asking that a special counsel be appointed to investigate alleged judicial and prosecutorial misconduct in the fugitive director's 32-year-old sex case.

They cited new evidence provided by the original prosecutor in the case who testified in a recent series of secret sessions that he tried to disqualify the original judge in 1977 on grounds of misconduct but was ordered by his superiors not to do so.

The lawyers also accused the current prosecutors of giving false information to Swiss authorities to support Polanski's extradition to the United States when they knew his potential sentence did not fall within Swiss requirements to order his return.
