We wish she had taken the stage for a Spice Girls concert, but we'll take her any way we can get her!

Geri Halliwell arrived at the Palaces theatre in London last night to put on a surprise performance of Gene Kelly's Singin' In The Rain as part of BBC Children in Need's project POP Goes the Musical, and she looked lovely in a black suit and white fur coat!

Ginger Spice reportedly nailed her impromptu musical number, and had tons of fun doing it! "Performing in Singing In The Rain in the West End was an absolute blast and a privilege to be lifted by the gorgeous Adam Cooper. The audience was fantastic, it was a dream come true," the 40-year-old was quoted as saying after the show.

Pop Goes The Musical is an initiative that has celebrities join the cast of well-known shows already performing. This fiery redhead's former bandmate Melanie C took the stage weeks ago to play the role of Mary Magdalene in Andrew Lloyd Webber's Jesus Christ Superstar.

Bravo Geri!

Steve Honig, Lindsay Lohan's publicist, has resigned.

Honig has been repping Lilo through her courtroom drama and run-ins with the law. Some of the most notable cases include her jewelry theft case, DUI charges and most recently, an alleged assault at a New York City hotel.

Another recent incident involved Linds and her mom Dina getting into a fight in front of their Long Island family home with the Mean Girls actress claiming her mom had used cocaine.

Honig, who also reps Brooke Mueller, released the following statement: "I'm not discussing this out of respect for my client."

A new rep for Lindsay has yet to step forward.

Seems Chris and Rihanna are trying to keep their relationship on the DL ...

Chris visited Rihanna at the recording studio Thursday night after Brown hit up David Furnish's 50th birthday party.

Our photographer tells us Chris parked on the street and entered through the front door of the studio, while Rihanna was parked in the private lot behind the studio and exited through the back door to avoid being photographed together.

He tells us:

"Chris was all happy, acting like he was just headed to work or something, but we knew he was visiting Rihanna. We even asked him, 'He; you going to see Rihanna?' and he just kind of laughed. You kinda get the feeling he likes sneaking around."

This is one of a handful of times the former lovers have reunited since Brown broke up with girlfriend Karrreuche Tran. Chris and Ri were spotted out together Oct. 4 at Jay-Z's Brooklyn concert at the opening of the Barclay Center and then we snapped the two together at the Qubeey launch party in LA last week.

Last night, RiRi held on tight to her favorite Gucci bag, while Chris stood out front next to his pricey Lamborghini.

Uh, Karreuche Tran ... who?

These two lovebirds can be so sneaky!

While leaving the Prince concert at the Sayers Club in Hollywood, Robert Pattinson and girlfriend pal Kristen Stewart climbed into their SUV ... hoping to not attract attention. Yeah, right!

The Twilight twosome haven't announced that their relationship is officially back on, however they've been hanging out a whole lot lately.

Hard to believe that just a few months ago, Rob and KStew split after she admitted to having a fling with married Snow White and The Huntsman director Rupert Sanders.

Wonder what Prince song is their favorite? Maybe "I Would Die 4 U."

On Thursday, Katie Holmes was grinning from ear to ear as she and her fellow thespians to discuss her return to Broadway in the play Dead Accounts at The Green Space in New York City.

The 33-year-old actress joined castmates Judy Greer, Josh Hamilton, Norbert Leo Butz and Jayne Houdyshell to talk to press about the dramatic family mystery production that's will begin their previews on November 3 and celebrate its grand opening on November 29 at Broadway’s Music Box Theatre. We're sure she's happy to go back to doing what she does best!

If looks could kill!

Yesterday, Kellan Lutz looked like a man on a mission as he left his hotel in New York City to hit the streets for a spell.

The 27-year-old Twilight actor slipped out of his formal wear after attending the 2012 GQ Gentlemen's Ball the night before. Wonder what kind of adventures this hunk got into?

Doesn't she look as good as her sister?!

Pippa Middleton was all smiles as she arrived with her closest family and friends, minus the Duke and Duchess of Cambridge, to the launch of her new book Celebrate: A Year of Festivities for Families and Friends at Daunt Books in London on Thursday.

The 29-year-old's 416 page party planning book comes complete with recipes, crafts and inventive ideas to help readers plan a variety of events from picnics to holiday gatherings.

“I feel incredibly lucky to be in this position to publish a book," Pippa said outside the event to a sea of journalist. "It’s been a crazy few years since my sister’s wedding. It’s had its upsides and its downsides and I feel really fortunate to build a career as a writer.” Great to see her ambitions are starting to pay off!

He's baaaack! And we're guessing he'll be snuggling up to ladylove Kristen Stewart in 3...2...

Rob Pattinson arrived at LAX this morning, and while he made a few Breaking Dawn press stops in Australia, K. Stew was in Japan promoting the film on her own.

Rob appeared on the The Kyle & Jackie O Show in Sydney the other day, and just as we suspected, he revealed that some of the scenes in the final Twilight film will blow our mind.

"The sex scene in this one is pretty ridiculous," he admitted. "It's just because you're kind of shooting stuff to be PG-13, and so it's just trying to think of inventive ways to try to make something sexy." He continued, "It's supposed to be about, like, the greatest vampire sex you've ever had. So a lot of it was just close-ups on me and Kristen's faces, but there was no one else there. You literally try and give a face of ecstasy ... guys' faces, I don't think, are really designed to do that… the cameraman was laughing as well."

Can't wait!
