Her sister is the future Queen of England, but that doesn't stop her from acting like your average commoner!

Pippa Middleton ventured out to grab some java in London yesterday, and the brunette beauty kept it casual in grey jeans, sneakers, a scarf, and sunglasses. It must be hard for the British bombshell to keep a low profile and lead a normal life now that she's a celebrity in her own right!

The stunning socialite accompanied her sister Kate to Wimbledon this past weekend, where they watched Rodger Federer defeat Andy Murray from the front row.

Miss Pippa is no stranger to high profile tennis matches! She used to frequently attend games with ex-boyfriend Alex Loudon, and rumor has it the former lovebirds might be reigniting their romance! The Duchess of Cambridge's little sister was recently spotted exiting Loudon's London home, causing people to speculate the former couple is back on!

"Pippa's delighted and so are the rest of the Middleton family. Alex makes her really happy," a source told Now magazine.

Is Prince William going to have a new brother-in-law soon?

Pippa Middleton could face jail time after a photo was snapped of her and several friends driving around Paris with a semi-automatic handgun pointed at photographers.

The 27-year-old sister-in-law of Prince William rode in the front passenger seat of an Audi convertible as the driver pointed a weapon at the shutterbugs, causing a concerned witness to file a formal complaint with Paris police. If the gun is real, the unidentified man holding it faces up to seven years in prison, and even if the weapon is fake, he'll still face up to two years.

Additionally, a law enforcement source tells Us Magazine, "If the evidence points to [Pippa Middleton's] involvement, she will be prosecuted. Anybody involved in the illegal use of a handgun in public is liable to arrest and interrogation." Yikes!

Justin Timberlake may be back together with Jessica Biel, but the 30-year-old actor/singer recently admitted that he has the hots of a member of the royal family!

"Us American males are big fans of Pippa [Middleton]," Timberlake told Esquire UK's latest issue. "We like the Middletons very much. I'm going to sound like a sleazeball. I'm going to stop right there!"

While Pippa may be flattered by JT's comments, she recently reunited with beau Alex Loudon, so we highly doubt a hookup between these two would ever happen, but who knows?! This is the guy who once dated Britney Spears...

Pippa Middleton worked classic black as she strolled through London on Monday.

The British beauty was clearly in business-casual mode in a black blazer, dress and short boots. Plus, she had not one, but two bags on her arm!

News surfaced Monday that Pippa, 28, and famous sister Kate will be the subject of a new E! True Hollywood Story. Can't wait to see how they grew up!

Rumors have been circulating that Prince Harry, 26, is dating Pippa Middleton, 27 -- the younger sister of Harry's brother William's new wife, Kate. Talk heated up after Pippa split from her banker boyfriend Alex Loudon a few weeks ago.

But Harry confirmed to The Daily Mail that he and Pippa are not an item. It seems the rumors are more what the public wants than what really is! Harry attended the Hard Rock Calling concert at Hyde Park in London Friday night, where he said he and Pippa's friendship is "strictly platonic."

"Pippa? Ha! No, I am not seeing anyone at the moment. I'm 100 percent single ... I'm working a lot at the moment, so dating and watching TV are the last things I have time for. I am hoping to get a holiday in August. I haven't been to South Africa in a long time, so maybe I'll go there."

South Africa is the home of Harry's ex, Chelsy Davy, 25. The two were schoolmates and dated on and off for years, and Davy attended William and Kate's wedding. But Harry is moving on -- a source told the Mail he spent much of the night at the concert in deep conversation with an American blonde.

See who else Harry partied with after the jump! Hint: it's the cast of a huge TV show!

Apparently being in her sister Kate's wedding to Prince William did not give Pippa Middleton the bride bug.

Pippa, 27, has broken up with her boyfriend Alex Loudon, 30, according to multiple reports from the UK. Loudon, a banker and former cricket player, was her date to the royal wedding in April.

Pippa has been spotted out and about with former flame George Percy lately -- including at a tennis match last week in London.

Who knew Pippa Middleton was such a tennis fan?!

While her sis Kate, now the Duchess of Cambridge, and Prince William were turning heads at the Epsom Derby in England, Pippa hopped the Channel and put in an appearance at the French Open.

And as heads bobbed left-to-right, following the tennis ball as it bounced between Rafael Nadal and Ivan Ljubicic, many eyes stopped to focus on the world's new "It" girl.

Middelton, 27, then jetted back to England to compete in the GE Blenheim Triathlon on Saturday. She's a sports fan AND an athlete!
