Oksana Grigorieva's London Bump

Mel Gibson's pregnant girlfriend Oksana Grigorieva was spotted arriving at her London hotel on Tuesday (Sept. 22) after appearing on GMTV to promote her new album.

Mel, 53, who filed for divorce in April (09) from his wife Robyn of 28 years, is expecting his eighth child with Oksana. This will be Oksana's second child. She is already a mom to 12-year-old Alexander, her son by James Bond star Timothy Dalton.

The 39-year-old musician told contact music she is feeling relaxed about their impending new arrival:

I've been a mother for 12 years so there's no first time mother's trepidation. Naturally, it's more relaxed and I'm very dynamic, so the pregnancy falls into my work schedule." She added that the pregnancy has strengthened her relationship with Mel, "How could I not be impressed by such an intimate connection with a miracle of life. Children are beautiful."

During her appearance on GMTV, Oksana said that she and Mel have no plans to wed: "Actually we have no plans to marry whatsoever. I haven't thought about it – we haven't spoken about it."

Mel and Oksana are expecting a girl this December.
