More Lohan Lunacy after this brief respite ...

SPLITSVILLE - POPULATION KATY PERRY AND JOHN MAYER: The KATY PERRY/JOHN MAYER on-again-off-again romance is off again. It sounds like it was a work issue. The couple have reportedly split for the second time in less than a year, but, as one pal told Us Weekly, "It's not over until it's over" -- meaning a third go round is possible.

Another source tells mag, "She's leaving the window open. They have both been so focused on work." The couple began dating last summer, but broke up in August before reuniting in September.

DID LINDSAY TRY TO HIT UP A CLUB HOURS AFTER JUDGE WARNED HER NOT TO DRINK OR DRUG?!: There's a new photo that allegedly shows Lindsay in the back of an SUV outside a club Monday night, just hours after the judge in her lying-to-cops case told her to stay away from alcohol and drugs. But the person in the photo is covering their head, and Lindsay says it wasn't her. (PHOTO)

According to TMZ, Lindsay hid under a sheet as the SUV she was in pulled up to the AV Club in Hollywood. But there were so many photographers there, she wound up leaving without ever going in. The back of an SUV, by the way, had a Mr. Pink Energy Drink logo emblazoned on it -- the same company that hooked Linds up with the private jet Sunday night so she could make it to the court hearing. TMZ says LoHo "obligated herself to attend events at clubs on Pink's behalf to pay off the debt."

Lindsay later insisted it wasn’t her in the car ...Tweeting, "Guys relax, that was NOT me at AV or in the @Mr. Pink SUV. I'm taking this seriously and focused on the road ahead."

True Dat Fact ... since turning 20 in 2006, Lindsay has spent most of her time on probation, out on bail or in rehab. And I think we can all agree, not nearly enough of it actually in jail.

DID MIRANDA LAMBERT CONFRONT SINGER OVER BLAKE SHELTON?!: The current issue of "Life & Style" floats the rumor that "The Voice" coach BLAKE SHELTON has been getting a little "too friendly" with a singer named Cady Groves, and that his wife MIRANDA LAMBERT confronted the little wannabe home wrecker.

But, judging from some back and forth Tweets between the two, it never happened. Blake laughed it off, Tweeting, "Hey @MirandaLambert . . . I just read in a tabloid that our marriage is falling apart!" Miranda played right along replying, quote, "Oh no! Can't wait to read if we make it or not."

QUOTE/UNQUOTE: "I think [ADELE is] f***ing great. She's not f***ing botox-faced, she's a normal, healthy girl who speaks in her native accent." -- OZZY OSBOURNE in a recent music blog interview. He adds he would, quote, "die a happy man" if he had the opportunity to collaborate with her.
