Peter Facinelli and Jennie Garth may be putting an end to their 11-year marriage, but it's not because either star had an affair.

"There are rumors out there which are completely untrue and hurtful to our family," Facinelli and Garth tell Us Weekly in a statement. "We just want to make it very clear, there are no third parties involved."

The couple met in 1996 while filming the movie An Unfinished Affair; they wed on January 20, 2001 and announced their split Tuesday.

The Nurse Jackie actor, 38, and the Beverly Hills, 90210 alum, 39, have three daughters: Luca, 14, Lola, 9, and Fiona, 5. "We both share the same deep love and devotion to our children," they told Us in a statement Tuesday. "We remain dedicated to raising our beautiful daughters together."

Post-split, Facinelli was spotted riding his Triumph motorcycle in L.A. Wednesday. Noticeably missing? His wedding ring.
