The Lethal Weapon 2 star wed her fourth husband, DJ Jeremy Healy, in April last year (09) but rumours have been rife that the union is in trouble.
Kensit's rep spoke out about the stories in February (10), confirming the couple has been taking some time apart, adding: "Patsy and Jeremy remain committed to making their marriage work."
But it seems the pair has failed to resolve its problems - and Kensit is selling the London home they shared, reports Britain's The Sun.
A source tells the publication, "They've done all they can to try to make it work. It has just fizzled out."
Kensit has previously been married to Big Audio Dynamite frontman Dan Donovan, Simple Minds singer Jim Kerr and Oasis star Liam Gallagher.
