Tori Spelling marks 50th birthday of BFF Jennie Garth: You are a sister to me

The girls of the famous series of the 90's, Beverly Hills 90210, have all grown up. Jennie Garth, who played Kelly Taylor in the series tracing the antics of a group of teenagers, passed a milestone last Sunday by celebrating her 50th birthday. A birthday highlighted by her best friend, Tori Spelling, who played Donna Martin in Beverly Hills.
Indeed, to mark the occasion, Tori shared an unexpected photo of the two ladies in aerobics outfits. 
And captioned the shot, She can kick... She can stretch... She's 50! commented Tori Spelling, 48. Sally O'Malley (referring to her role on the Mystery Girls series)... Oops, I mean Jennifer Eve Garth, you really embody a human being where a number is just a number, she continued. You are more beautiful today than you were 30 years ago. You are an amazing and inspiring woman. Such a great mom. You are my mentor. I love you so much. You are a sister to me. Xo.
