More legal issues are heating up Hollywood today, as stars face the travails of justice on both sides of the Atlantic.

Chris Martin got a strong warning from the British police and the paparazzi got a strong warning from Martin's wife, Gwyneth Paltrow. Police officially cautioned the Coldplay lead singer for attacking a photographer who tried to snap a picture of him and Gwyneth.

Now, for the first time, Paltrow is fighting back to protect her new baby, Apple. “It's just not right,” she insisted. “I'm doing what I can to take evidence. I'm keeping track of who they are, taking evidence of who they are.”

And there's a different kind of fight brewing in Lindsay Lohan's family. The hot young star should be having the time of her life, but instead, the bitter conflict between her parents continues to escalate. Lindsay's father, Michael, showed up to court Wednesday, claiming his estranged wife, Dina, tried to run him over on Tuesday night.

But Dina says it was her husband who tried to run her over and that police had to escort her home. Michael Lohan was back in court Thursday on charges of punching a sanitation worker.

Finally, more bad news for Courtney Love: While in a Beverly Hills court for her drug possession case, lawyers tried to serve her with yet another lawsuit. A travel agency now claims she stiffed them out of nearly $50,000.

Love refused to take the papers, letting them drop to the floor. Meanwhile, her drug trial was pushed back to November.
