Kim Richards turned 51 this weekend (September 19) and sister Kyle Richards was right by her side celebrating the occasion. The ladies of the Real Housewives of Beverly Hills posted several adorable pictures on social media — including an epic throwback of the two — as well as shots from Kim's birthday dinner at Lisa Vanderpump's West Hollywood restaurant PUMP.

The outing is a sign the sisters are in a good place, following Kim’s recent legal issues and battle with sobriety. From the photos, it appears everyone was all smiles — including Kim's children who are also present in several shots. 

Also in attendance was Kim's ex-husband Monty Brinson, sister Kathy Hilton, and her husband, Rick.

Lisa Vanderpump was more than happy to be a part of the celebration. 

And another Beverly Hills Housewife spread the birthday love. Check out Yolanda Foster's sweet well wishes for Kim.
