Katy Perry, Robert Pattinson, FKA Twigs Attend Children’s Benefit in Beverly Hills

Katy Perry, Robert Pattinson and FKA Twigs attended the 8th Annual GO Campaign Gala at the Montage Hotel in Beverly Hills on Thursday.

The 31-year-old "Dark Horse" singer sat beside the couple at the children's benefit and took photos with them, according to the Daily Mail.

Perry and Pattinson have been close friends for years. They became even closer as they were going through break-ups with their significant others. Pattinson split from his high-profile actress girlfriend Kristen Stewart in 2012 and 2013, when photographs of Stewart cozying up to director Rupert Sanders were released.

Perry offered him support during the difficult time. In return, Pattinson was Perry's shoulder to cry on when she first parted ways with John Mayer.

Pattison and his fiancée FKA Twigs were dressed in black and white for the event, which was dedicated to helping children in need. Perry donned a black dress with colored polka dots and paired the look with vintage dropped earrings.

A source told Us Weekly in September that Twigs, 27, and Pattinson, 29, were "excited to be married."

"Twigs is still enormously happy with Rob and they aren't rushing to have the wedding," the source added. "Things couldn't be better."

The pair announced their engagement in early April after just six months of dating.

Since their engagement, there have been several rumors circulating that there's trouble in paradise for the couple, but the source insisted these speculations were untrue.

Perry, who just concluded her Prismatic World Tour on Oct. 18, recently attended Allison Williams' wedding in September.

A source told People then that Perry and Mayer were "definitely back together," despite their on-again, off-again tendencies.

"John and Katy looked happy," the source told the magazine. While the two stars arrived on separate private jets, the source added, "They held hands and sat next to each other during the wedding ceremony."

Perry released her last album, "Prism," on Oct. 18, 2013. The album produced the singles "Roar," "Unconditionally," "Dark Horse," "Birthday" and "This Is How We Do."
