Pippa Middleton arrived at her boyfriend Alex Loudon's London home last night in a printed dress but left for work this morning in a denim number. Alex was right ahead of her in a buttoned-down shirt as they headed off to work, but she first threw some luggage into the trunk of her car. It seems things are still going well for the couple despite stories circulating that Pippa Middleton and Prince Harry are dating. Alex and Pippa have been seeing each other for nearly a year, though he wasn't her date to her sister's wedding on April 29. Pippa's had a seriously packed schedule since then, spending her weekends in France or Spain and at weddings or various athletic events. Harry and Alex aren't the only guys giving Pippa lots of attention. Even Usher wants Pippa, as the singer recently said he thinks the "beautiful" and "stunning" 27-year-old would be a perfect model for his new lingerie line.
