Marilyn Manson has proposed to his girlfriend of five weeks

The 43-year-old rocker presented actress and filmmaker Seraphim Ward, 27, with a family ring, thought to have belonged to his grandmother, last Thursday (12.04.12), according to friends.

A source told Life & Style magazine: "Marilyn proposed with a family ring. I think it was his grandmother`s. It`s Celtic, and Seraphim says it has a magical bonding to the receiver."

Seraphim`s representative added: "Seraphim is in a committed relationship and is over the moon about what her bright future holds with her partner."

Yesterday (15.04.12), the actress tweeted a picture of a diamond encrusted Claddagh ring - a traditional Irish ring given as a token of friendship, love, or marriage - with the caption "OMG! (sic)".

She later added: "I am still speechless and in shock!"

On her twitter page Seraphina describes herself as "a Independent Occult Filmmaker and a Industrial Goth Rock Artist (sic)" and pals say she and Marilyn bonded over their shared interest in the supernatural.

The friend added: "They share an interest in the occult and have bonded fast. He`s gotten her a house in the Hollywood Hills."

Marilyn was previously married to Dita Von Teese and engaged to both Rose McGowan and Evan Rachel Wood.
