London, Dec 11 - Former "Friends" star Jennifer Aniston recently visited an orphanage in Mexico, fuelling speculation that she is planning to adopt a child.

The actress took a low-key trip to the Casa Hogar Sion orphanage in Tijuana, reported contactmusic.com.

"Aniston got on with all the children, but spent most of her time with the babies. She loved them. She was in the nursery for a long time playing with them," said Carmen Gonzalez, co-founder of the orphanage.

She and her ex-husband Brad Pitt have both donated money to the institution. Aniston's visit follows weeks after it was reported that the actress is keen to start a family.
