Strange goings on in the volatile world of rap. Miami Beach tough guy Lil Wayne has hired security guards to keep a round-the-clock watch over his ex-wife and their daughter.

He plunks down more than $10,000 a month to ensure the safety of BET reality star Toya Wright, whom Wayne divorced in 2007, and their teenage daughter, Reginae.

Why the beefy dudes? It’s weirder than you think.

Wright, 28, star of Toya: A Family Affair, got hitched last year to record producer Mickey “Memphitz” Wright.

So happens Memphitz has been accused of domestic abuse — so My Homies Still singer Lil Wayne wants to make sure someone’s on hand to keep Memphitz on the straight and narrow.

The allegations of abuse, repeatedly denied by Memphitz, have been a prominent storyline on the current season of VH1’s popular Love & Hip-Hop Atlanta. They were made mostly by R&B star and cast member K. Michelle, a former Memphitz squeeze.

“You bet that Lil Wayne is concerned,” a source in Memphitz’s camp tells Gossip Extra. “He mostly wants to make sure their daughter never gets caught in the middle of anything.”

Memphitz’s spokeswoman had no comment.

Missing dog

Supermodel Adriana Lima has made an impassioned plea to thousands of her fans to help her find her beloved pooch — a two-pounder that could be roaming the neighborhood around Marlins Park right now!

The Victoria’s Secret angel, 31, lives with ex-NBA player hubby Marko Jaric in a $9 million mansion in fancy Indian Creek Village.

But when she flew to New York to deliver their second baby last week, Lima dropped off her Maltese at the Little Havana home of a friend.

Then, the worst-case scenario: pooch Ivy bolted out of the friend’s house and disappeared.

People have been calling Crime Stoppers to report sightings of the teacup dog — last seen around the new stadium.

“There’s no crime involved,” said Miami-Dade Sgt. Rufus Boclair, Crime Stoppers coordinator. “There’s nothing we can do.”

And since Lima’s tweets are getting desperate — “I’m in tears,” she tweeted Thursday night — here’s our contribution to the search effort: Call 305-387-3131 with information about Ivy, not Crime Stoppers.

There’s no word of a reward.

‘housewives’ update

The producers of the second season of Bravo’s The Real Housewives of Miami, scheduled to premiere Sept. 13, struck gold.

Not only did they hire supermodel Joanna Krupa to revamp a relatively boring cast, but they’ve also found Lisa Hochstein.

The 29-year-old Hochstein, a resident of Miami Beach’s Sunset Islands, obviously combines the grace of the former Playboy model that she is with slight touch-ups by her husband of three years. He is well-known plastic surgeon Lenny Hochstein.

In the premiere, Lisa tells her fellow cast members while she shows off her $6 million house: “This house was built by boobs!”

Marysol Patton, Alexia Echevarria, Lea Black and Adriana de Moura and new members celebrity chef Ana Quincoces and dentist Karent Sierra round out the cast.
