Friday, April 29^th, the much anticipated marriage between Prince William and Catherine Middleton was officiated before the world, and in appropriate royal fashion there were no mishaps apparent — aside from what could’ve been an embarrassing catastrophe that is.

Shortly after the now Duke & Duchess of Cambridge left Westminster Abbey in their royal carriage en route to Buckingham Palace, a spooked horse threw its rider and began a rampage toward the carriage. Cueing the national coverage to quickly cut–check out the footage below.

Catherine, allergic to animals, looked alarmed yet was reassured by her Prince, er Duke (pun intended). Neither the horse nor the rider were hurt.

Melissa Rivers came through “On Air With Ryan Seacrest” to offer some food for Ryan Seacrest and Ellen K, but hung out for a while and gave her insight on The Royal Wedding’s Dos and Don’ts.

The first fashion Do was the very yellow, “peep looking,”  Queen Elizabeth. “She looked like a happy little grandma. Like an easter egg,”  Said Melissa as she continued to say “She looked cuddly.”

Katherine Middleton‘s sister Pippa Middleton looked extravagant, regardless of wether she was wearing white or not. “I’ve never worn a bridesmaid dress that i looked hot in” Melissa jealously admitted in regards to how pretty Pippa looked. Melissa then added “I personally think it was a little Va-Voom.”

Melissa let Ryan and Ellen know what she thought Prince Harry‘s girlfriend Chelsy Davy appeared to look. “She looked like she snuck out of clearance house with her underwear in her purse at 5am and ran home and got ready …like last nights make-up”

I say ‘hi.’ I’m friends with them.” He also adds, when asked about his royal powers, that “I think the most important power is to use [your power] to make it better for everybody else.

Piers Morgan phoned in from London to “On Air with Ryan Seacrest” to chat Royal Wedding details and what he anticipates will be the most talked about aspect of the big day.

As a Brit himself, Piers described Friday, April 29th, as, “the most magical day I’ve ever experienced in my own country,” adding what he thinks will be the most-talked about element of the day as the second kiss between William and Catherine which took place on the designated balconey.

Piers explains, “nobody in the history of the royal family has gone on that balconey and has ever kissed their wife twice…the second kiss propelled William and Catherine into royal history.”

Piers also offered us the low-down on what William and Catherine will be doing this evening, sharing, “it’s been described as the mother of all knees-up, which is a party organized by the best man Prince Harry and the brides sister Pippa Middleton and all I can tell you is large disco balls have been seen entering the palace….the Queen is leaving Buckingham palace she isn’t having any of this…and then the young royal turks including Sarah Ferguson kids Beatrice, Eugenie, Prince Harry and all the other young cousins, nephews, and nieces are all going to get stuck in a long party and we’re told Harry at 6 o’clock tomorrow morning is planning a bacon butties party which is basically bacon sandwiches for all the stragglers still left standing.”

Casey Abrams was able to escape being sent home after judges used their save to keep him going into the Top 11, but unfortunately, his time on ‘American Idol‘ ended last night. Abrams wasn’t too surprised, however. He told ‘On Air With Ryan Seacrest‘ that he knew he would be sent home, he was “feeling it.”

Abrams said he was a little weary after a duet with fellow contestant, Haley Reinhart, and that may have affected his performance. However, Abrams said he had a “blast performing, and went out with a bang.”

During his very last ‘Idol’ performance, Abrams was caught locking eyes with Reinhart. When Seacrest asked if there was something more to that look, Abrams responded “No, no. That look is exactly what it looks like. It’s just ‘hey, i’m going to miss you. And i’m going to miss singing jazzy duets with you.’”

Abrams said his goal was to make it to the top 6, and that’s exactly what he did. He will be performing his first post-idol performance at the KIIS-FM studios today. He says his only request he wants while performing are hot dogs.
