Update: It's on now! Be sure to tune in to see the stars arrive!

Big news, Potter fans: YouTube will be hosting a Harry Potter and the Deathly Hallows red carpet live stream on July 7 straight from London's Trafalgar Square! The live stream will kick off at 8 a.m. PDT, where you'll get a chance to see the entire cast of Harry Potter as they walk the red carpet alongside celebrity guests from across the globe. YouTube is even offering up the entire Harry Potter movie collection for rent for $3-$4, so you can catch up (or re-watch) before the final film hits theaters on July 15. It's the next best thing to attending live across the pond, unless you win our red carpet experience that is.

But even if you miss the London premiere on July 7, don't fret — you'll have another chance to see the stars on the red carpet as PopSugar will be bringing you live coverage from the US premiere in NYC.

You could be trekking all the way across the globe (and dropping some serious cash) to witness the spectacle that is the royal wedding, but the good news is you don't have to travel to jolly old England to get in on the action. Thanks to technology and a few livestream options, you can watch the entire thing unfold right from your couch and for a lot less money. Check out these apps, sites, and tools that will let you in on a little royal wedding fun at home.

• Tour Westminster Abbey — A new iOS and Android app ($4.50) lets you tour a virtual replica of Westminster Abbey, where William and Kate will be saying their vows. Also included in the app are points of interest, so you can stop and take a look from all angles. Who needs an invite?
• Get updates on Twitter — There may be a rule against cell phone use during the ceremony, but you'll still be able to get up to the minute updates about the royal wedding on the official Clarence House Twitter page.
• Watch it live — You have three solid options for watching the royal wedding live online, so even if you don't have cable, you'll be covered.
• See the royal procession route in 3D — No need to battle the crowds after the ceremony, just check out the sights on Google Earth instead! Taking you on a virtual 3D tour of the postwedding parade, you'll see sights like Big Ben, Parliament, and Buckingham Palace, where the reception will be taking place.

Let's hope Omar really does start a long and lucrative career in makeup design.

Remember the JK Wedding Entrance viral video from 2009? It's been spoofed in the past by such TV shows as The Office, but now T-Mobile has added another twist to the spoofing action: the upcoming royal wedding. Called the T-Mobile Royal Wedding, this video that went viral over the weekend, depicts lookalikes from the royal wedding party — right down to Prince Charles, Camilla, Queen Elizabeth, and Prince Harry — dancing down the aisle in fine form.

As fun as the dancing is, I can't get over how the "fake" wedding party looks just like the real ones, Camilla and Prince William especially. And since the wedding precession breaks all traditional rules, other established ones go right out the window as well — these invitees can't help but break out their smartphones to film the action. That's a no-no according to official etiquette guides. Check out all the T-Mobile behind the scenes goodies after the break.

Notorious tech-savvy artist Lady Gaga, who at one point had the biggest video on YouTube, is gearing up to answer questions from fans — and you can be a part of it! She will take text and video questions via her YouTube channel and answer a selected amount of questions via YouTube video.

To submit a question, visit Gaga's YouTube channel and upload your video or text question. You can also vote on the questions you'd most like to hear, so she can get to those answers right away. Or, you can tweet your question using the hashtag #GoogleGoesGaga. She seems open to any question, but ask quickly — the submission deadline for questions is this Friday, March 18.

Check out the announcement in Gaga's own words after the break.

In an effort to improve the quality of its content, YouTube may start adding content created by celebs. A report says that the newly-instated YouTube CEO wants celebrities to control certain verticals on the site, contributing original three-minute "shows" specifically for the YouTube audience.

The reasoning: that this high-end content will keep both viewers and advertisers happy and encourage even more quality content on the site — turning it into a serious programming destination and not just a place to watch funny cat videos. There's a lot of money at stake too, with rumors saying that YouTube could offer chosen celebs up to $5 million to run and produce specific channels.

Since celebs are already producing their own content and posting it through various outlets, this seems like a natural fit and a very smart move for a very popular site.
