According to Entertainment Tonight, Grant asked LA to marry him, after she moved in with him in Venice. The couple were on the beach together for a work out before Grant got down on one knee to propose.

The proposal parallels with The Flash star's story line, as his alter ego, Barry Allen, also proposed to his girlfriend, Iris West.

"Barry was kind of re-establishing his confidence in the relationship. Not letting his fear dictate things, but rather let his heart dictate things, which he's always done in the past," Gustin said last month. "So we're kind of back to true-form Barry, I think. As much as we can be with what he's dealing with right now."

Recently, Grant was seen in Vancouver filming final scenes of season three of The CW show.
