The American actress also made waves last year after she and husband Chris Martin announced their "conscious uncoupling" to the dismay of fans.
The pair appear to have stayed on good terms, even going on holiday to the Hamptons together in the summer, however Gwyneth recently revealed that she still has doubts regarding their split.
"We've made a lot of mistakes, and we've had good days and bad days," she told Harpers Bazaar. "But, I have to say, I'm proud of us for working through so much stuff together – and not blaming and shaming."
"Of course, there are times when I think it would have been better if we had stayed married," she added. "Which is always what your children want. But we have been able to solidify this friendship, so that we're really close."
