In Touch previously revealed the couple had a difficult time conceiving, and eventually resorted to IVF treatments — even though the decision was difficult to make.

"They had been trying for a baby all summer and it just wasn't happening, so they sought the help of a fertility doctor," the source continued. "George has never had any trouble doing anything in his life, plus Amal is afraid of needles, so her biggest fear was getting the hormone injections."
