Real Housewives

Question is ...

One day there will be a story about Josh Waring from "The Real Housewives of Orange County" that does NOT involve him getting arrested.

This is not that day.

TMZ has learned Waring was picked up in Irvine on Friday night on a warrant for a probation violation.

Waring was also busted in June 2008 (possession of heroin and ecstasy and intent to sell), July 2009 (possession of narcotics and drug paraphernalia), and April 2010 (battery on a spouse or significant other and false imprisonment, both misdemeanors).

Bellino -- who stars on "The Real Housewives of O.C." -- posted a blog saying, "Our girls were in their stroller and I thought I had put the brake on, but apparently I didn't." As TMZ first reported, the parents weren't paying attention ... and the stroller rolled into the pool.

The reality star then explains that her husband "instantly" jumped in after the kids and plucked both of them out of the water before their heads went under the water.

Sources at the pool tell TMZ that sometime during the holiday celebration, Alexis and her husband Jim were off "doing something" ... and the stroller -- carrying 2 toddlers -- toppled into the pool.

According to multiple security officers on scene, the lifeguard pulled the stroller out of the water with one child still in it. Alexis' husband dove in to save the other one.

But Jim tells us a slightly different story -- claiming, "There was no lifeguard needed or involved."

Sources close to Staub tell TMZ the 46-ish-year-old won't name the partner -- her boyfriend at the time. We're told he signed off on the tape but wants to keep his identity under wraps.

We can understand why he doesn't want a credit for his handiwork ... but we were able to find a fleeting frame of the dude's reflection in a mirror.

Staub hit the famous Scores Gentleman's Club -- where she enjoyed some XXX scenery with another lady friend.

Jacqueline -- who used to be close with Staub -- tells us she's "not surprised at all" that Hustler Inc. claims they are all set to distribute a sex tape featuring the mother of two with a mystery man from September 2009.

She tells us, "I'd be very happy if [Staub] left our show ... Why doesn't she just leave and go do porn?"

Jacqueline adds, "Danielle has total disregard for how [the tape] will affect her daughters' impressionable years."

While neither are pirates, both were raised in New Jersey.

Hustler tells us it is all set to distribute a 75 minute tape, featuring Jersey's most hated Housewife -- and mother of two -- in a naked romp with a mystery man.

A rep from Hustler tells us the tape was shot last September -- several months after 47-year old Staub first appeared on the Bravo reality show. The tape is set to be released on June 14.

A rep for Staub had no comment on the story.

More real life drama for the "Real Housewives of Orange County" -- this time, Tamra Barney's son is behind bars after cops made a major discovery during a minor traffic stop in the OC.

TMZ has learned Ryan Vieth -- whose traffic problems have been chronicled on the show -- was taken into custody Wednesday night after cops pulled the guy over ... and then learned there was an active warrant out for his arrest.

Law enforcement sources tell us Vieth had missed a recent court appearance in connection with a prior traffic problem -- so he became a wanted man.

Ryan is being held on $15,000 bail -- he's scheduled to face the judge later today.
