Meanwhile, it looks as if Robin and ex Paula are managing to find a way forward in their custody battle over Julian.

Latest reports indicate that despite a bitter court battle, the two have now decided to try and co-parent together and are close to working out an arrangement they can both agree on.

The former couple met when she was 15 and he was 14, and dated for 10 years before getting married in 2005. The actress filed for divorce in October 2014.
