Keanu Reeves was seen giving his girlfriend Alexandra Grant a loving kiss goodbye on Sunday, as she dropped back to his Berlin hotel to continue filming The Matrix 4.

 The couple chatted briefly, before they waved goodbye to one another and Alexandra returned to her rented property, where Keanu stays every weekend during breaks from filming the highly anticipated movie.

The Matrix 4 will be released in 2021 and production began in early January with Lana Wachowski returning as co-writing and director, and while filming stopped in Berlin in March the stars were returning to the German capital in June.

When the new movie was announced, Lana said in a statement: 'Many of the ideas Lilly and I explored 20 years ago about our reality are even more relevant now...

'I'm very happy to have these characters back in my life and grateful for another chance to work with my brilliant friends.'

Aleksandar Hemon and David Mitchell co-wrote the Matrix 4 script alongside Wachowski. Keanu is again playing Neo with Carrie-Ann back as well.

The Matrix 4 will also also feature Yahya Abdul-Mateen II, who's best known to audiences as Black Manta in 2018's Aquaman.
