On Saturday night, Robert Pattinson and Katy Perry spent time together as they attended a Bjork concert at the Hollywood Palladium in Los Angeles.

Robert Pattinson and Katy Perry were said to have met up “discreetly” and made their way into the gig together before leaving separately to avoid photographers waiting outside the venue, X17Online.com reports.

Katy Perry, 28, opted for a gothic inspired ensemble for her evening out with her showbiz pal, teaming a punky leather miniskirt with a black and silver crucifix logo T-shirt.

She teamed her outfit with a long black satin coat, black tights and heels, while wearing a black and silver choker around her neck.

Showing off her perfect porcelain skin with natural make-up, Katy Perry wore her raven locks poker straight around her face.

And in spite of her A-list pal, Katy Perry paid no reference to her company as she expressed her delight at the gig over Twitter, writing: “Dear Bjork, how do I join your traveling girl cult? #brilliantshow.”

Katy Perry and Robert Pattinson have been spending a lot of time together in recent weeks, and it’s even been claimed the songstress has even taken her pal to visit her parents in Santa Barbara, California.

A source told Grazia magazine: “Katy and Robert have been spending a lot of time together recently and it’s safe to say there is serious chemistry. Katy thought the break from LA would do Rob good, and since he was no longer living with Kristen, she didn’t hesitate in inviting him to join her.”

“But she doesn’t want to ruin their friendship by rushing into anything.”

Katy Perry and Robert Pattinson puzzled onlookers earlier this month when they were spotted checking out the wedding rehearsal of two strangers at San Ysidro Ranch, not far from where Katy grew up.

Rehearsal guest Stephanie Sands told People.com: “Katy and Rob were just sitting next to each other watching the wedding rehearsal in the main courtyard area. They were dressed very casually.

“She was wearing a hoodie and big sunglasses. There was no PDA between them and no body language that showed they were dating. They just sat together and watched. They were not affiliated with the wedding party and were not seen mingling with guests.”

Katy Perry was said to have been disapproving of Robert Pattinson’s reconciliation with Twilight co-star Kristen Stewart last year following her fling with married director Rupert Sanders.

A source told Life & Style magazine: “Katy never really supported Rob’s decision to get back with Kristen. She always said they wouldn’t last.

“Katy told Rob she didn’t think their relationship could withstand the cheating scandal. And he deserved better than someone who would destroy a family [like Rupert’s].”

Despite the couple managing to patch things up after a two-month break following Kristen Stewart’s “momentary indiscretion” with Rupert Sanders last year, it is thought their relationship is over for good this time after Robert Pattinson was spotted moving his belongings out of her home in Los Feliz earlier this month.

Meanwhile, Katy Perry split from musician John Mayer in mid-March, but the on-off couple are recently said to have rekindled their turbulent romance.
