AceShowbiz - Rihanna has stunned the crowd at London Art Gallery with a surprise visit. On Tuesday evening, July 12, the "Love The Way You Lie" singer was caught on camera making a public appearance at the Mexican Geniuses Exhibition at Dock X in Canada Water two months after welcoming a baby she shared with boyfriend A$AP Rocky.

In a picture shared on Instagram by Fever UK, the 34-years-old songstress could be seen rocking black top with lace sleeves, paired with black pants and white sneakers. Also wearing a statement medallion around her neck and letting her hair down in curly waves, she made herself comfortable while posing on a wrought iron park bench.

Accompanying the "Umbrella" singer's photo, Fever UK wrote in the caption, "We found love in an artsy place." It added, "Last night, @badgalriri visited @themexicangeniuses exhibition in #London and she met (virtually, at least) one of her idols, #FridaKahlo. We are SCREAMING INTERNALLY."

Rihanna was reportedly in London to give support for her beau Rocky, who was scheduled to perform at Wireless Festival. On May 13, the twosome, who have been romantically linked together for two years after being friends for several years, welcomed their first child, a baby boy, together.

Although Rihanna looked like she was ready to get back to her usual routine, a source explained that she was still not prepared to introduce her baby to the public eyes. "Rihanna is not quite ready to debut her baby to the world just yet," the insider told Hollywood Life, adding that she was "extremely protective" of the infant and that "he's still very young and she's still managing the transition to motherhood."

Rihanna and Rocky have been keeping a low profile after welcoming their baby boy together. Before the London trip, a source close to the couple claimed the "Diamonds" singer had been resting together with her baby at their home in Los Angeles. "Rihanna is doing well. They are very excited to be parents. Rihanna is already a wonderful mom," the source further spilled to PEOPLE.
