Pink ‘celebrated’ her marriage split with a raucous night out in Hollywood on Monday.

And Pink was not in the mood to mourn her marriage - she got the party started when she jumped onstage to join rockers Metal Skool, who perform at the venue every Monday night.

It isn’t the first time Pink has joined the group onstage - she teamed up with the tribute act onstage in 2006.

Key Club regulars spotted the pair “making out” and “looking very together”, according to In Touch.

Radiohead, Tom Petty and the Heartbreakers and Jack Johnson will headline a music festival at San Francisco’s Golden Gate Park in August.

The inaugural Outside Lands Music & Arts Festival, which aims to feature rock, blues, reggae, jazz, hip-hop, world, soul, Latin and electronic on five stages, will take place August 22-24 at the 1,000-plus acre venue.

Additional acts will be announced in the coming weeks. Tickets will go on sale at the end of March, with pricing still to be worked out. Organizers hope to draw about 60,000 fans on each of the three days.

Johnson, who has ruled the U.S. pop charts for the last three weeks with his album “Sleep Through the Static,” is one of the headliners at the Coachella festival in southern California (April 25-27). Additionally, he and Radiohead top the bill for the inaugural All Points West festival near New York City (August 8-10).

The rap-rocker pleaded not guilty Monday to a misdemeanor count of simple battery stemming from a fight at an Atlanta-area Waffle House last October.

Rock, 37, did not appear in court and had his attorney, Darryl Cohen, enter the plea on his behalf.

The singer (real name: Robert Ritchie) and members of his entourage ran into trouble at the breakfast-purveying chain in the wee hours of Oct. 21, following a concert at the Tabernacle concert hall in Atlanta.

While at the restaurant, a woman who was with Rock’s group allegedly got into a heated debate with another Waffle House patron whom she recognized.

The two apparently took their quarrel into the parking lot, where Rock and five members of his entourage became involved before piling onto the rocker’s tour bus and departing.

Police stopped the bus shortly thereafter and took Rock and his cronies into custody on a single charge of simple battery. Rock was released later the same day after posting $1,000 bail.

During an appearance on Ellen DeGeneres’ talk show later that same week, Rock maintained that he had been provoked into participating in the encounter, adding that he did not consider himself to be a violent person.

“The last thing I want is that reputation,” he said. “I believe in just standing up for things I believe in, and being honest, and sometimes it gets me in a little bit of trouble.”

Now that the Spice Girls reunion tour has ended, Melanie “Sporty Spice” Chisholm is getting ready to release her fourth solo album in April.

“This Time,” on her own Red Girl imprint, will come out in the U.K. on April 2 and in Canada six days later. It marks the follow-up to 2005’s “Beautiful Intentions,” her final release for Virgin Records.

Chisholm — who also goes by the name Mel C — has been on the road since December 2 with the Spice Girls. The 47-date trek ended in Toronto on Tuesday. Along the way, Chisholm performed solo acoustic shows in New York and Los Angeles. She plans to play some Canadian dates in May.

Before all the publicity from the reunion, little had been heard from Chisholm in North America following the success of her solo debut, 1999’s “Northern Star,” which sold close to 3 million units worldwide. Her next two albums, “Reason” (2003) and “Beautiful Intentions,” were not released in the States.

Chisholm describes “Beautiful Intentions” as a rockier release, and says she wanted to do something different on “This Time,” which she calls “mature pop.” The first single, the upbeat pop track “Carolyna,” tells the story of a young runaway, but it’s the only issue-oriented lyric on the album.

“I think most of the songs on this album are more about relationships and personal feelings and fears and experiences,” she says, including being a child of divorce (”Your Mistake”) and love conquering all (”The Moment You Believe”).
