Sideshow: A July royal baby, a pranked queen

Too much about the royal pregnancy already? How could there be? More news!

Catherine, Duchess of Cambridge

, is due in July! Reputed Kate-pal

Jessica Hay

tells Life & Style the royal couple decided to couple royally in September, near the end of their royal tour. Nice, Jess: Make sure we know

just when

William and Kate were doin' it. And now, icky, but funny: Aussie radio folks

Mel Greig

and

Michael Christian

of station 2DayFM are apologizing big time. They impersonated

Queen Elizabeth II

and

Prince Charles

on the phone and

actually got through

early Tuesday morning to the nursing staff at King Edward VII hospital in London, where Kate is being treated for severe morning sickness. Said staff told the faux-Liz II of Kate's progress, which the radio Aussies put on the air. Not nice!

Nice book news, with Philly ties!

Frankie Muniz

(

Malcolm in the Middle

) is 26, yet he was on Twitter of late, to write: "I was in the hospital last Friday. I suffered a 'Mini Stroke,' which was not fun at all." He continued, "Have to start taking care of my body! Getting old!" Frankie is better now.

Rose Byrne

and

Bobby Cannavale

are a couple. Scariest people on TV, Rose as the ambiguous Ellen Parsons in

Damages

and Bobby as the draconian Dr. Michael Cruz on Showtime's

Nurse Jackie

, plus tragic monster Gyp Rosetti on HBO's

Boardwalk Empire

, which ended its season in a blaze, or should we say spurt, of glory on Sunday. In real life, they are said to be all boofangle and lovey-woops.

Brains prolapse over Harry Styles and Taylor Swift, seen boppin' 'round NYC, strolling Central Park, singing karaoke at the party after One Direction's Madison Square Garden foofaraw! Blogger Perez Hilton said he even saw a physical impossibility: Taylor and Harry "exiting the same hotel minutes in between each other!!" To quote Manuel of Fawlty Towers: "Qué?" Meantime, and we do mean mean, Hailie Scott Mathers, daughter of Eminem, tweeted a request to Taylor that she "stop whoring around with every guy you see." Intemperate!! By the end of the day, due to blowback, she was flail-backpedaling, "it was just a bit of fun," oh, sure, hahahahaa. . . .

Extraordinary intellect Chris Brown, touring Europe, and Instagram, posted a bunch of fotos of himself getting stoned out of his tree in Amsterdam, where it's legal. Chris with three blunts in mouth! Chris blowing cloud-shapes! Chris about to "dab" (inhale cannabis-oil fumes)! Also pics of himself with (on-again gf?) Rihanna, restoking world rumor mills. . . . Forrest Liebenberg, that poor guy comedian Katt Williams slapped in a Seattle-area Target recently, has been fired from his job. What? Why? "How dare you be slapped by a raging stand-up comedian?????" . . . Nick Lachey got into a tussle at Sunday's San Diego Chargers-Cincinnati Bengals game at Qualcomm Stadium. He was officially invited to be elsewhere. He tweeted later he "couldn't be prouder" of the honor. TMZ says someone insulted Nick's former boy band, 98 Degrees. Nick denies reports he choked a fan and hurled vile imprecations at a lady.

Do not misquote

Jack White III

. NME butchered his remarks about

Lady Gaga

, and it ended up sounding like a diss. Much ire at Jack early Wednesday. So the Whitester told British Esquire, and thus the world: "I never said anything about her music, or questioned the authenticity of her songs in any way." He says his topic was "the drawbacks of image for the sake of image. . . . Peace to Lady Gaga and I fully congratulate and compliment her on her championing of gay rights issues and the momentum it's given to help create change."

Tuesday's "SideShow" erred in reporting the timing of cameos by

Sens. John McCain, Barbara Boxer,

and

Olympia Snowe

and

Vice President Biden

on NBC's

Parks and Recreation

. In fact, all have appeared, the solons in this season's Sept. 27 opener, and the veep right after the election.
