Jennifer Aniston made a top-secret visit to a Mexican orphanage, according to a new report.

The actress – and inadvertent poster girl for desperate, single woman of a certain age – reportedly spent time with the little'uns at Casa Hogar Sion, a rundown baby refuge in Tijuana.

It's claimed the star has been supporting the refuge since she was with ex-husband Brad Pitt, and plans to return to adopt one of the orphans.

"Jen has been ploughing money into the orphanage for years, just as her ex Brad has, and to adopt a baby from there makes perfect sense,” a source tells the UK's Now magazine.

"She and Brad will never be - she knows that - but this bond through the baby will live on, no matter what. Brad and Angelina can never escape from that."

The orphanage's owner Carmen Gonzalez is quoted as saying: "She 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 and cuddling them."

The magazine's source adds: "This is what she's always wanted, a baby, and now it's about to come true.

"She won't let anything get in the way of her dream."

Jen has almost been a mother for, oh, years now so excuse us if we don't hold our breath for this one to "come true."
