FKA twigs and Robert Pattinson reignite split rumors after she was spotted without her engagement ring. The couple arrived together at Los Angeles International Airport on Monday evening, September 26.

In some photos obtained by X17online, FKA's sparkler from Robert was noticeably absent from her left hand. The "Water Me" hitmaker donned black sunglasses, a black leather jacket over a crop top and white overalls. Robert followed his fiancee behind, wearing a black hat, sunglasses, a hoodie, jeans and white shoes. He carried a big brown backpack.

A representative for FKA and Robert hasn't commented on why she ditched her engagement ring.

Meanwhile, Robert and his ex Kristen Stewart may reunite on-screen as Lionsgate's co-chairman Patrick Wachsberger doesn't rule out making more "Twilight" films. "It's a possibility," the L.A.-based Frenchman told ScreenDaily, "Not a certainty but it's a possibility. It's about Stephenie [the 'Twilight Saga' book author Stephenie Meyer]. If she wants to tell a story related to those characters we're here for her."

Robert was recently hit with gay rumors. A hoax site called Now88News published a supposedly "exclusive" interview with the British heartthrob in which he admitted to "a secret holiday romance with 31-year-old male model Brad Owens."

Back in June, Robert was rumored to be back with Kristen following her split from Soko.
