The 27-year-old has become the centre of post-wedding gossip and has been dubbed "Her Royal Hotness" by avid fans and the British media.
"Everyone is raving about the 27-year-old brunette dubbed Her Royal Hotness, now and for ever more," read the Daily Mail.
London newspapers are making the most of the public's interest in Pippa by publishing a stream of stories about her love life and "flirtations" with Prince Harry. The Mirror and People newspapers have both featured her on their front pages.
There has been speculation that she and Prince Harry shared some chemistry during the wedding, despite Pippa dating London broker Alex Loudon.
Harry reportedly leaned over during the ceremony and whispered: "You do look very beautiful today, seriously."
They were also seen exchanging "flirty glances" on the balcony of Buckingham Palace.
Pippa's shapely figure has also become a hot topic online, inspiring fan sites like The Pippa Middleton Ass Appreciation Society, which has over 100,000 fans on Facebook.
Twitter is also being used to spread the word with thousands expressing their admiration for the bridesmaid.
"Pippa Middleton, best body at the wedding other than David Beckham," tweeted @iamToddyTickles.
"This wedding has mainly been about Pippa Middleton's amazing arse, hasn't it?" wrote @caitlinmoran.
Wedding rumours are now beginning about Pippa, with the Daily Mail reporting she is secretly engaged to her boyfriend Mr Loudon.
It is claimed the wedding has been kept a secret for fear of detracting from Kate and her big day.
But with Kate's day over, she is now courting her own press, but not everyone is keen to jump on the Pippa bandwagon.
