David Spade and Naya Rivera enjoy dinner date

Actors Naya Rivera and David Spade have fuelled rumours suggesting they are dating after enjoying a luxury dinner date in Malibu, California.

The unlikely couple first sparked speculation about a romance in late March (17), when the former Glee beauty was snapped getting close to David in a hotel pool while in Hawaii, where the comedian was on tour with pals Adam Sandler and Rob Schneider.

Spade subsequently played down the cosy pictures, but it appears the two stars' budding relationship appears to be heating up after they were photographed stepping out for another date in Malibu on Thursday night (20Apr17).

TMZ cameramen spotted the pair heading to top sushi restaurant Nobu, where Naya was seen wearing a sexy black dress and matching high heels.

However, her choice of outfit, which featured a revealing slit in the front of the skirt, left the actress struggling to maintain her modesty as she walked, forcing her to use her right hand to hold down the material to avoid the paparazzi snagging a crotch shot.

Spade is the first man the 30-year-old mother-of-one has been romantically linked to since filing for divorce from husband Ryan Dorsey in November (16) after two years of marriage. They are parents to son Josey, who was born in September, 2015.

Spade has an eight-year-old daughter named Harper with Playboy model Jillian Grace, while he also briefly dated another actress, Heather Locklear from late 2006 to early 2007.

Although Naya's apparent relationship with David may have come as a surprise to fans, Heather recently offered up her own thoughts on how the Joe Dirt star, 52, manages to land pretty dates, suggesting he wins them over in the bedroom.

"He's always with beautiful, famous actresses," she told TMZ.com.

"Number one, he's funny. Number two, he has a big c**k," the 55-year-old joked.
