Why ride one motorbike when you can have two? Bradley Cooper spends the day playing with his expensive boys' toys

He really loves his motorbikes.

Prior to a night out at Kate Hudson's Halloween party with his 21-year-old girlfriend Suki Waterhouse, Bradley Cooper hopped on yet another one of his collection of bikes on Saturday - a KTM Superbike.

The 38-year-old actor hit the Los Angeles roads on his black, white and orange two-wheeled beast, looking like something out of Transformers.

Nobody could say that Bradley cuts corners in the safety department, as he dressed himself head-to-toe in armour-like ensemble for his weekend zip around the city.

Fiercely solid shoulder pads with silver futuristic trimmings completed his sturdy black leather jacket, which he zipped all the way up before mounting his speedy friend.

Black trousers complete with hefty knee pads and black and white biker shoes made up the rest of the biking aficionado's ensemble, with a smooth black helmet ensuring he was ready to join the Los Angeles roads, which tend be filled with drivers of questionable ability.

As he gripped the handles with robotic gloves, the Silver Linings Playbook actor was sure to perform a head check before lurching out into traffic.

Hours later, Bradley ditched that motorbike and hauled out another from his collection, to transport he and his girlfriend Suki Waterhouse to Kate Hudson's Halloween party.

His costume for the evening was that of an actual gorilla, while his much younger girlfriend kept things sexy in leopard print tights.

The star will continue dominating Hollywood as he takes on the role of executive producer on upcoming television series Limitless, based on a film by the same name which he starred in back in 2011.

He will adapt the project along with Relativity Media, and the CEO of the company - Ryan Kavanaugh - spoke with Variety about it earlier this month.

'Limitless is the perfect example of Relativity’s multiplatform approach to creating quality content,' he said, adding: 'The story will transition perfectly to television, and we’re excited to partner with such a talented actor and producer as Bradley Cooper on the series.'
