London loves LeAnn Rimes -- and the feeling is mutual. The 30-year-old country singer took the stage Sunday, March 17 to perform at the Country To Country Festival at London's O2 Arena and blew away her British fans.

According to the Daily Mail, Rimes started crying on stage when fans gave her a standing ovation following her emotional concert. "Wow, all I can say is wow!! London, I love you so much!," she tweeted, later adding, "I cannot get over the amount of love from the O2 and London!"

Rimes, who took the stage in a tight black dress with sexy cut-outs, performed a few of her hits like "How Do I Live" and a memorable rendition of "Amazing Grace." "You were amazing yesterday," one fan tweeted at Rimes. "Thank you for giving so much to us, made a huge arena feel like a living room! Amazing Grace."

The singer's husband Eddie Cibrian, 39, was also in attendance at the show. An eyewitness tells Us Weekly that the proud hubby was watching from the side of the stage and "taking video of her standing ovation."

After her successful show, Rimes was ready to return to the States and move into her new home with Cibrian. The couple, who wed in April 2011 after ending their previous marriages, purchased a $3 million mansion in L.A.'s Hidden Hills community in December 2012. The 8,642-square-foot property features six bedrooms, a gated pool area and gourmet kitchen.
