Sadie's not happy with reunion

It can't have been easy for Sadie Frost when her ex-husband got together with a gorgeous blonde 22-year-old actress after they split. But then he went and slept with the nanny and that was the end of that.

But now Jude Law and Sienna Miller, now 28, have got back together and they're diving straight back in head first, if reports are to believed. There is apparently a summer wedding in the works and they are 100% sure this time that they want to grow old together.

This renewed closeness extends not just from Sienna to Jude, but also from Sienna to Jude's three kids - whose mum is Sadie.

Sources say Sadie is not too chuffed with how Sienna has fallen straight back into the role of step-mother to the kids. And after Sienna took Jude's son to have his haircut, resulting in his blonde curls being lopped off, Sadie was mighty annoyed.

So much so that the usually discreet actress took to her Twitter and wrote, "I think ya should get ya own child and then cut their hair."

But Sadie obviously regretted her decision straight away as she then deleted her whole Twitter account.

So far neither Jude or Sienna have commented.
