Real Housewives of O.C. star Alexis Bellino nearly faced tragedy on the Fourth of July when two of her children fell into a pool.

Security at The Balboa Bay Club in Newport Beach, Calif. tell  that Alexis, 32, and her husband, Jim, were off "doing something" when a stroller carrying 2 1/2-year old daughters Melania and Mackenna rolled into the water. (They are also parents to 4-year-old son, James.)

Witnesses say the lifeguard pulled the stroller out of the water with one child still in it. Jim dove into the water to save his other daughter.

But Jim told the site, "There was no lifeguard needed or involved."

Neither child needed medical attention.

Alexis posted a poolside photo of herself and one of her daughters wearing matching bikinis on Facebook and wrote: "It's all about family on the Fourth of July!!!!!!!!!"
