What a rock!

"Glee" star Naya Rivera showed off her impressive wedding ring after tying the knot in a surprise ceremony last month.

The 27-year-old actress stepped out for some errands on Tuesday, where we got a good look at the massive sparkler from new husband Ryan Dorsey. She also sported skinny jeans, a white tank-top and a Raiders hat -- a nod to her brother, Mychal Rivera, who plays for the Oakland team.

Rivera and Dorsey said "I Do" in July at Las Ventanas al Paraison resort in Cabo San Lucas, Mexico. The wedding came as a shock to fans of the "Glee" star, as she had just called off her engagement to Big Sean back in April.

"Ryan has always been spontaneous … and we didn’t question him," the grooms father tells toofab. "We are very happy for him. We trusted them and want what they wanted. They chose to do the wedding that weekend because his birthday is July 19th and it was a wedding gift to him."

According to TMZ, July 19th was also the date she had picked for her wedding to Big Sean.
