'Millionaire Matchmaker' Hottie Candace Smith -- My Ass Loves Ball Sports ... That's No Stretch!

"Millionaire Matchmaker" star Candace Smith made the perfect love connection on an L.A. beach Tuesday ... between her ass and the paparazzi.

Candace -- a former beauty queen -- hit the sand for some volleyball and a pigskin toss (looks like she has game) ... with her pal ex-Miss USA Susie Castillo.

Like all finely tuned athletes ... Candace knows nothing's more important than stretching. Well, that and a very small bikini.
