Kathy Hilton and her husband, Rick Hilton, had a pretty major reason to celebrate over the weekend, and Kim Richards made sure she didn't miss out on the chance to fête her sister and brother-in-law. So, what was the big deal happening in the Hilton household? Well, it just so happened to be the 25th anniversary of the launch of Hilton & Hyland, Rick's real estate firm which he opened back in 1993 with business partner Jeff Hyland.
Oh, did we forget to mention that Paris Hilton was also on hand for the festivities? Obviously she took some time out of her busy schedule to applaud her parents' accomplishments — and Kim made sure to post a photo from the event, as well as a sweet message: "Had so much fun celebrating 25 years of H&H the other night [with] dancing, singing... SO FUN!! Love my family!"
There have been a lot of family parties for Kim as of late, who was also on hand at a bash celebrating Mauricio Umansky's real estate company, The Agency, alongside her The Real Housewives of Beverly Hills sister Kyle Richards, for their seven-year anniversary earlier this month. Now this is one successful family!
