A source close to the model told HollywoodLife.com Tran was "frantic" when she heard about Brown's medical emergency around 1 a.m. local time Friday and immediately called him to make sure he was OK.
“She couldn’t believe it, she thought the worst and cried,” the source said. “She was relieved after that and told him to take care of himself and that she wished she could be there for him."
Hours after the seizure, Tran took to her Twitter account, and while she didn't explicitly mention Brown in her posts, she called for "Prayers all day" and said she had a lot on her mind alongside an Instagram photo of herself.
Brown's representative issued a statement saying the singer met with his doctor, who blamed the seizure on fatigue and stress from constant negativity.
