American actor and filmmaker George Clooney's wife, Amal Clooney has sparked rumours that she is pregnant. The 38-year-old civil rights lawyer, who wore a yellow sweater and embroidered bell bottoms, as she visited her husband on the Los Angeles set of his latest movie, displayed fuller figure starting pregnancy rumours. George is currently directing the upcoming film Suburbicon.

This comes after In Touch magazine claimed that Amal has begun IVF treatments. An alleged source close to the couple said: "Amal will be starting in vitro fertilization next month. Given their ages — Amal's 38 and George is 55 — the doctor said they need to start right away because time isn't on their side."

The Gravity star and the British-Lebanese lawyer tied the knot in 2014, in Venice, Italy. The couple who recently celebrated their second wedding anniversary, do not have any children yet.

Previously, during an interview with ET's Nancy O'Dell, Clooney could not stop gushing about his barrister partner. He said: "She's an amazing human being. And she's caring. And she also happens to be one of the smartest people I've ever met. And she's got a great sense of humour. There's a number of reasons why."

The Oscar winner also talked about Amal's sense of style. Clooney said: "It's amazing, because she's always – since the day I met her – she's always had this insanely...it's eccentric but it's fun, sense of fashion. How she does it while she's got 11 cases she's working on, and she was teaching at Columbia, and she's still like, 'I want to wear that dress.' It's crazy. It has been sort of fascinating to watch, because she has such great taste."
