Another one bites the dust!

Kate Hudson has called off her engagement to fiancé Matt Bellamy, X17online can report exclusively. The actress hasn't been spotted wearing her engagement ring since the LACMA gala in early November, and they have been spending almost all their time apart.

The musician did not attend Thanksigiving festivities with the blonde beauty and her family and friends, nor did he accompany her to Art Basel just last week. In fact, last night the Grammy winner was drinking and partying at the Koko club in London, while the Almost Famous star enjoyed a night on the town with pals at The Nice Guy nightclub in L.A.

The only time the pair have been in the same place in recent weeks was for Kate's mother Goldie Hawn's MindUp charity event in Beverly Hills on November 21, but the only reason the British hunk was in attendance was because he was on the host committee and wanted to keep up appearances.

A source tells X17online exclusively:

    "Kate doesn't ever want to get divorced again, and she wasn't sure marriage with Matt was the right choice. There is still a lot of love there, and they plan to amicably co-parent their son. Who knows what the future holds for them, but right now it's not a wedding."

The 34-year-old actress and the Muse rocker became engaged in April 2011 and welcomed son Bingham three months later.
