Ellen DeGeneres may have turned 57 yesterday, but she certainly didn't look it as she walked the beach with her wife Portia DeRossi.

The legendary TV host took to Twitter to share a sweet picture of herself and Portia enjoying a sunset stroll in California with the caption, "My last sunset of 56 with my favourite person."

Ellen and Portia have been together since 2004, and they married in Beverly Hills in 2008, shortly after California's ruling against same-sex marriage was overturned. 

The Ellen Show's 13th season kicked off yesterday, with Keith Urban, Olivia Munn and Joe Biden showing up to pass on their birthday wishes to the presenter. Actress Olivia even brought trays of take-away food as a 57th birthday gift:
