Garth was visibly missing from Elba's side at both Screen Actors Guild Awards and Indie Spirit Awards, reported Ace Showbiz.
There's no other details about their separation.
Elba walked alone on the red carpet of Independent Spirit Awards.
Back in January, he was accompanied to Screen Actors Guild Awards by his 15-year-old daughter Isan, whose mother is his ex-wife Hanne "Kim" Norgaard.
