Pippa's back!

Recently returned from a family vacation to Mustique (Duchess Kate couldn't join them) Pippa Middleton spent Sunday in the English countryside in Hertfordshire -- to cheer on her boyfriend, Alex Loudon, at the Cricketers Cup Finals.

The 27-year old socialite showed off her deep tan and famous figure in an orange dress, and intently watched Loudon (a finance whiz who was once a professional cricketeer) play with Eton Ramblers. See more photos of Pippa at the Cricketers Cup Finals.

"She was really passionate about the game and looked proud when Alex shone during certain moments," an onlooker tells Us. (Despite a brief split in early summer following the royal wedding, the couple of two years reunited in June.)

And Middleton even brought lunch! "She had packed a wicker hamper with sandwiches, juices, fruit and other snacks," a witness says.

 When the game was over -- after nearly seven hours of play! -- "They weren't hiding their affections," the witness says. (Sadly, Loudon's team lost in the final round.) "She ran up to him and hugged him. She called him darling and he kissed her briefly. They're a cute couple."
