There's a new, serious development in the soap opera that is Jesse James' love life (as if his shocking, secret Nazi comedy pics weren't serious enough).

Last year, the motorcycle man ended a five-year marriage to Oscar winner Sandra Bullock -- and relocated to Texas to raise his kids near her -- after an infidelity scandal involving Michelle 'Bombshell' McGee. This year, he proclaimed his love for a new fiancee, 'L.A. Ink' star Kat Von D.

Now, RadarOnline reports that ex-wife Janine Lindemulder, mother of his 7-year-old, Sunny, has been arrested outside Austin, Tex., after allegedly leaving a slew of "harrassing" voicemails on James' phone. A Hays County sheriff's deputy confirmed the arrest.
