Paul Walker was renowned for being an adrenaline junkie, who revelled in the high-octane stunts on Fast and Furious, but he was also a quintessentially handsome movie star; the Steve McQueen of his age, referred to fondly by Vin Diesel's character as "the most beautiful blonde here."

His She's All That co-star Rachel Leigh Cook described him as "a grounded surfer, who never fell prey to the trappings of his celebrity."

Indeed, while other stars are plagued by press intrusion, Walker seemed to achieve the rare feat of keeping his love life firmly under wraps. Little is known about his private life, and with tributes flooding in for the much-loved actor, there is speculation as to his relationship status.

According to Who's Dated Who, the "Fast and Furious" star was in a long-term relationship with actress Genesis Rodriguez at the time of his passing.

"Genesis started dating Paul in 2012 and was his last girlfriend before he died in a car accident in November 2013. The beautiful and up-and-coming actress Genesis Rodriguez hit the big screen in an upcoming suspense/drama film with Paul Walker," Who's Dated Who reports.

While their relationship has not been confirmed, the What to Expect When You're Expecting actress has not posted anything on Twitter since Walker's passing.

40-year-old Walker was previously known to have had a string of celebrity girlfriends, but kept his personal life away from media attention.

He had a 15-year-old daughter named Meadow, with Rebecca McBrain who he dated in the late 90s.

On becoming part of the Hollywood circuit, he was later romantically linked with several celebrities, including model Jaime King, Christina Milan, who he had a brief romance with in 2000, and his Into the Blue co-star Jessica Alba, who he met while shooting the film in 2003.

Alba expressed her sadness at his loss on Instagram, saying: "#RIP#PaulWalker He was such a sweet and grounded guy -my heart goes out to his family #sosad."

He was briefly linked to Denise Richards, but his last known girlfriend was Jasmine Pilchard -Gosnell. The couple were reported to have got engaged in 2008, but the rumours proved false and they broke up soon after.

Rarely commenting on his real life relationships, in a recent interview with WENN Walker spoke about the on-screen loves of his life saying: "As for the girls, I legitimately love Jordana (Brewster). We met when we were little kids hanging out on the first one (Fast & the Furious) when she was 17 years old. Michelle (Rodriguez) and I, we've been through it all. Michelle's like the most original person on the planet. She's so straight up, uncensored all the time. Be ready. I love her for that."

The actor's Fast and Furious co-stars have each been expressing their profoud sense of loss on his passing. Jordana Brewster tweeted quite simply: "Paul was pure light. I cannot believe he is gone."

Walker had been attending a fundraiser for Reach Out WorldWide when he was involved in a fatal car accident in Santa Clarita, California yesterday (November 30).

The actor was the passenger in a Porsche, which collided with a telegraph pole. Both the actor and the driver were pronounced dead at the scene.

Walker is survived by his 15-year-old daughter Meadow.
