His last trip to Las Vegas made headlines around the world, but he obviously had a good time because Prince Harry is rumoured to be planning another visit.
According to the Daily Star, Prince Harry is so delighted by the news that he's going to be an uncle that he's already considering heading back to Sin City to wet the baby's head.
A US military source told the Daily Star that Harry's friends are encouraging him to head back out there when his current tour of duty in Afghanistan is completed.
The source said: "A lot of the boys are trying to get Harry to go on another trip to Vegas when their service is done."
During Prince Harry's last visit, in August, he was photographed naked with some scantily clad young women, after playing 'strip billiards' in his penthouse suite at the Encore at Wynn hotel.
As well as being hugely embarrassing to both Prince Harry and the royal family as a whole, his party-packed trip also raised security fears about how well he was protected during his holiday.
However, Las Vegas tourism officials were delighted by his antics. According to the New York Post, the leaked photographs gave the Nevada city a $23million (£14million) boost in tourism.
His visit also inspired a cheeky tourism board ad campaign, reminding visitors that "what happens in Vegas, stays in Vegas."

City break guide: Las Vegas
Is Prince Harry planning another trip to Vegas?
Now, by Strip show, we're talking taking a walk down the long road that is the heart of Las Vegas, to see the most bizarre collection of hotels in the world. Marvel at the ostentation of Paris Las Vegas with its half-scale replica of the Eiffel Tower, New York New York and its very own Statue of Liberty, Excalibur, with its fairytale turrets, and the Luxor, guarded by the Sphinx.
Catch sight of the world's craziest water feature at the Bellagio. Throughout the day, jets of water spiral and shimmy on the hotel's vast lake to a soundtrack including "Luck Be a Lady Tonight" by Frank Sinatra and "Time to Say Goodbye" by Andrea Bocelli and Sarah Brightman. If you're on the Strip in the evening, check out the Treasure Island hotel for another free spectacle, watching sexy sirens and pirates do battle on a tall ship.
The latest, 21st-century interpretation of Vegas is City Center, a cluster of hotels and casinos on the strip that cost $8.5bn to build, the most expensive project of its kind in American history. One of many wow factors here is the shopping mall, Crystals, which is crammed with the world's top brands. When you've finished gawping at the audacious facade (a heap of "crystals" in glass and metal) go inside the three-storey mall for some high-class shopping at names including Louis Vuitton, Bulgari and H Stern.
Relax at the spa at the Mandarin Oriental in City Center, one of just 20 in the world to have received the prestigious Forbes Five Star award. This exotic spa, its design inspired by 1930s Shanghai, has 17 treatment rooms and a hydrotherapy suite with hammam. Therapies are just as indulgent, combining ancient and modern techniques, informed by traditional Chinese medicine.
Vegas caters for every taste, including the most discerning gourmets. And one of the best places to put this city's culinary arts to the test is at Michael Mina in the Bellagio. The Michelin-starred restaurant serves a la carte and tasting menus to die for, where you can indulge your taste buds with lucious ingredients such as Kobe beef, lobster, truffle and foie gras.
Where do old signs go to be revived? The Neon Museum. Examples of this quintessential Vegas art form are preserved and exhibited at The Boneyard, which you can visit by appointment, and out in the city around Fremont Street, where you can take a self-guided tour to see refurbished treasures including the Hacienda Horse and Rider and Aladdin's Lamp.
You can't visit Vegas without taking in a show. And there are always plenty to choose from - big names now in town include Barry Manilow, Celine Dion, Jerry Seinfeld, Cher and more. For a performance as fantastical as the location, check out one of the eight amazing acrobatic shows currently being performed across the city by the Cirque du Soleil.
This is cowboy country and you can see them in action at the Thomas & Mack Center, home of the annual Wrangler National Finals Rodeo and the Professional Bull Riders World Finals. Tickets are like gold dust for these annual competitions, but there are plenty of other exhibition rodeos, too, where you can catch sight of a bucking bronco.
The Vegas wedding chapel is the king of the kitsch wedding - they say a couple ties the knot in this town every five minutes. Pledge your troth at a drive-through ceremony, in a gondola, or at a chapel in the clouds. There's no end of memorable locations in which to say "I do". And, of course, even Elvis will perform the ceremony for you.
Take to the skies with Heli USA. Get a bird's eye view from a helicopter of the desert and the Hoover Dam, before a thrilling swoop through the Grand Canyon, setting down at a ranch at its rim for a horse ride cowboy style. Or hire a car and drive out to the Skywalk, a glass-bottomed viewing platform that extends over the edge of the mighty canyon for views that will doubtless take your breath away.
