Robert Pattinson has been openly dating Tahliah Barnett for months, and a source has revealed that the "Twilight" actor and singer more popularly known as FKA Twigs were actually set up by a celebrity couple!

According to a report from E!Online, Robert Pattinson started dating Tahliah Barnett after he watched her concert with actress Sienna Miller and her husband, Tom Sturridge.

The hunk actor reportedly enjoyed the British singer's music, which led to Sienna Miller and Tom Sturridge "playing cupid" for the two!

The E!Online report also added that Robert Pattinson and Tahliah Barnett were recently spotted on a date at West Hollywood's Soho House.

An insider detailed: "They were with a big group of friends, sitting at a table in the garden dining area, about 10 people."

"They sat on a couch together totally flirting, holding each other's hands and kissing here and there. (They were) really cute and they seemed super happy! They were there for about an hour," the source narrated.

Robert Pattison dating Tahliah Barnett is the actor's first seemingly serious and publicized relationship after he broke up with "Twilight" co-star Kristen Stewart last summer. The ex-couple's split came after the actress' alleged cheating scandal with her married "Snow White And The Huntsman" director, Rupert Sanders.

According to a report from Hollywood Life, Kristen Stewart was reportedly mocked at an FKA Twigs concert.

The dissing incident allegedly took place during the English electro-pop singer's October 9 concert in Bristol, United Kingdom. An audience member suddenly yelled: "F**k Kristen Stewart."

As a response, the edgy singer did not say anything, but let out a visible smirk.

However, an eye witness during the concert clarified that FKA Twigs did not intend for the smirk to be misinterpreted as rudeness.

"The smile was not out of anything remotely close to smugness," the insider said, reported by Hollywood Life.
