Kim & Kyle 'The Closest We've Maybe Ever Been

Kyle and Kim Richards have been through quite a bit and had their ups-and-downs, but neither of them would have predicted the thing that would mend their relationship and bring them closer than ever would be ... high diving?

The Real Housewives of Beverly Hills duo spoke with People on Wednesday about their current status, as well as their time together on Stars in Danger: The High Dive, which premieres tonight on Fox at 8pm EST. Apparently, facing your fears of belly-flopping can do quite a bit of good for familial struggles, because according to big sister Kim, she and Kyle are " probably the closest we've maybe ever been ... I really didn't see any light at the end of the tunnel."

Kyle agrees, saying that Kim helped her overcome her worries during diving practice. "The first day I had to get on the diving board, I was completely overcome by fear ...  felt like I was going to faint. I couldn't feel my legs ... My sister felt very protective of me and kind of went into mama-bear mode ... We really had to support each other and I think that's the best thing that's come out of this for us. Kim and I are definitely in the best place we've been since we were little girls."
