Gwyneth Paltrow is the latest celebrity attempting to turn back the clock by giving her bust a boost, according to US reports.

Chris Martin's missus is well known for her perfect pins and yogarific figure but has never been able to boast an ample cleavage - until now.

The actress appears in the latest edition of Gotham magazine alongside trainer Tracy Anderson to talk about her new health regime and looks slightlier curvier than usual in the accompanying photo spread.

An expert in the field of plastic surgery tells Page Six, "She didn't use to have anything up top.

"Now she does, and they are perky."

But after giving birth to two children we reckon Gwyneth's rounder chest is just the result of aging gracefully.
