Actress Jennie Garth put her marriage split blues to one side on Thursdaynight (19Apr12) to celebrate her 40th birthday and the launch of her new reality farm life TV show A Little Bit Of Country with her former Beverly Hills, 90210 castmates.

Shannen Doherty and Ian Ziering joined the revellers at the London West Hollywood to salute Garth, who is still recovering from her shock split from husband Peter Facinelli.

The star's three daughters with Facinelli - Luca, 14, Lola, 9, and five-year-old Fiona - were also there for mom.
