London: Actress Amber Heard was spotted with her rumoured boyfriend, the South African-born Canadian-American billionaire Elon Musk, at a club here. The actress, who has been navigating her way through a very public divorce from estranged husband Johnny Depp, and the Tesla Motors CEO were spotted exiting The Box club in London on Tuesday night. They were there alongside "Suicide Squad" stars Cara Delevingne and Jared Leto who were present for the premiere of the film, reports aceshowbiz.com. For the outing, Heard wore a black dress that she teamed with a black hat and ankle boots, while Musk looked casual in a grey shirt and a blue suit. The pair sparked dating rumours during a vacation in Miami last month. Heard and Musk reportedly hung out together a lot during their stay at the Delano Soth Beach in July. The actress, who was with her sister at the time, was seen multiple times entering and exiting his room. However, multiple sources have shot down rumours about her and the Tesla founder being an item.
