May 1 (UPI) -- The Flash star Grant Gustin is engaged to girlfriend LA Thoma.
The 27-year-old actor shared a photo with his fiancée Saturday on Instagram after proposing to Thoma on the beach.
The picture shows Gustin and Thoma smiling as the bride-to-be shows off her diamond ring. Sources told Entertainment Tonight Gustin popped the question during a workout in Venice, Calif., one day after Thoma moved in.
Gustin and Thoma have been dating since January 2016. The couple celebrated their engagement Sunday by attending an NBA playoffs game between the Los Angeles Clippers and Utah Jazz.
"When you're about to see the @laclippers in some court side seats for the first time ever. With your FIANCÉ. Thanks for thinking of me WB. LETS GO CLIPS!!!" the actor wrote.
Gustin plays Barry Allen, aka Flash, on The CW series The Flash, which is in the midst of a third season. The character got engaged to Iris West (Candice Patton) for a second time on The Flash and Supergirl crossover episode in March.
"Barry was kind of re-establishing his confidence in the relationship," Gustin told Entertainment Tonight the same month. "Not letting his fear dictate things, but rather let his heart dictate things, which he's always done in the past."
