Mills claimed she was "so, so happy," with the decision, but events inside the courtroom seem to tell a different story.
According to various accounts in the British press, Mills allegedly lashed out at McCartney's high-powered attorney, Fiona Shackleton, pouring a glass of water over the solicitor's head.
The U.K.'s Daily Mirror declared "Wet It Be" on its front page, breathlessly recounting the splash-and-dash. "[Heather] was so angry, she tipped a glass of water over Fiona Shackleton's head, leaving her with soaking wet hair," one insider told the paper. "Everyone was stunned. That kind of behavior is just not acceptable."
Indeed, pictures from the courthouse show Shackleton arriving Monday morning with a bouncy blonde bouffant and leaving at around 2 p.m. with damp locks slicked back behind her ears.
When the BBC asked Mills about the alleged attack, the Dancing with the Stars vet would only say that Shackleton had been "baptized in court." (Shackleton's office at Paynes Hicks Beach had no comment.)

"[Shackleton has] very sadly handled this case in the worst manner you can ever, ever imagine," Mills said. "She has called me many, many names before even meeting me."
David Rosen – who has been working for Mills as a solicitor advocate – told reporters Tuesday, "I think [Mills] felt Fiona Shackleton had behaved ... in an undignified way." Although he didn't "quite see" Monday's incident, Rosen added, "I just heard the trickle."
Mills suffered another setback in court Tuesday morning, when she lost her bid to keep the divorce settlement under wraps. The full 58-page judgment was released soon afterward. (Click here to see the full judgment.)
