Madonna brings on the “Guilt Gifts” as rumors persists that her marriage is dead as doornail after an affair with Alex Rodriguez.

The Material Girl dropped $25,000 last week on a vintage BMW motorcyle and sidecar as a “Just Because I Love You” gift to hubby Guy Ritchie.

“Madonna took time to find out what would really wow Guy,” an inside source tells Star. “Then it dawned on her. He told her years ago that he’d always wanted one of those WW-II-era bikes. So she had her assistant track one down.”

The tabloid snitch says Madonna is more committed to making her marriage work than ever before, adding she “is more in love with him than ever. He’s extremely loyal to her. She knows she’s lucked out.”
