Rihanna, Pippa Middleton and Sandra Bullock Lead Today's Star Sightings

Hollywood has taken over England in the past 24 hours. Rihanna, who’s currently on the European leg of her Diamonds World Tour, was spotted at a bowling alley in Manchester. The 25-year-old superstar rocked Big Star USA “Heather” overalls while enjoying a night out on the town.
Elsewhere in England, Pippa Middleton looked lovely in a green ensemble as she watched the Men’s Singles second round match on day four of the AEGON Championships. Middleton, 29, recently published a piece on her best Wimbledon experiences for Vanity Fair (where she is a new contributing editor).
Finally, Sandra Bullock turned heads on the red carpet for the gala screening of her new film The Heat over at the Curzon Mayfair in London. The crime comedy, also starring Melissa McCarthy and Tony Hale, opens stateside June 28.
Back in Hollywood, a pregnant Busy Phillips enjoyed some sunshine while out for lunch, Britney Spears carried her own bags after shopping at a crafts store in Calabasas while Matthew Morrison stopped by The Grove for an interview with Extra.
