Ready for a big night in the entertainment world, the 2012 BET Awards are all set to take place in Los Angeles, CA tonight (July 1).

Making a surprise appearance ahead of her slated Sunday headlining duties, Rihanna joined mentor Jay-Z as he closed out Day 1 of BBC Radio 1's Hackney Weekend in London, England on Saturday night (June 23).

Held at Hackney Marshes, the black crop top clad Barbadian beauty stepped onstage while helping to kick off the 42-year-old rap star's set with an energizing rendition of their hit collaboration "Run This Town".

They love to travel together, and Beyoncé Knowles and Jay-Z were seen out and about in Paris, France this afternoon (June 7).

The “Empire State of Mind” rapper and his “Crazy in Love” wife headed back to their hotel to get ready for Jay’s Watch The Throne gig with Kanye West.
