Justin Bieber and Rihanna took to the runway for The Victoria's Secret Fashion Show on Wednesday night and as they were getting ready for their performances, they tweeted messages to their fans and also added some thank you's at the end of the night. 

Rihanna performed "Diamonds" and "Fresh Out the Runway" from her new album "Unapologetic." The songstress wore a black dress with a split up the front for one performance and a pink lingerie set for another.  She posted photos on her Instagram and Twitter of her getting ready for the show and also backstage with the Victoria's Secret Angels. 

While spending some time with the girls backstage, she posted on her Twitter, "1 big room, full o bad b--ches," "My b--ches pretty in pink" and "I'm a #VS girl now lol." She also included the hashtags #backstagelife, ##phuckyoamateurmodeling and #LEGITmodelsh--t.

Bieber, 18, performed an acoustic version of "Beauty and a Beat" and "As Long as You Love Me." All throughout the day he tweeted about his excitement to perform at the annual fashion show. He posted "tough life @Brunomars," who also was one of the night's performers. Bieber's performance during the PINK section of the show made one model extremely excited. 

Karlie Koss said she is a big fan of Bieber and Lilly Aldridge posted on Twitter, "I have Bieber fever!"

The show was held at New York City's Lexington Armory. 

This year's $2.5 million Floral Fantasy bra, created by London Jewelers of New York, was worn by supermodel Alessandra Ambrosio. Unlike years before, the bra comes with a belt and a diamond-encrusted perfume bottle cover. The bra features two detachable flower pins, and a drop centerpiece that has a 20-carat white diamond, a 12-carat white diamond and a 21-carat pear-shaped ruby. All three items in the Fantasy set together rank up a total of $3 million, according to a London Jewelers spokesperson.

It took over 150 hours to make the handset bra which has 186 carats of stones, all handpicked. The set includes amethysts, tsavorite, sapphires, rubies, and white, pink and yellow diamonds, all set in 18 carat rose or yellow gold.
