X17Online posted photos on Saturday (Feb. 15) of Katy Perry and John Mayer out for Valentine's Day with the "Roar" singer sporting a suspicious piece of jewelry: a gold ring worn on her wedding finger.
The 29-year-old fueled rumors that she and Mayer were ready to tie the knot as they headed to dinner at Sunset Tours Hotel in Los Angeles.
Back in November, a source told E! News that engagement was "inevitable" for the "very serious couple."
Another source told E! that Mayer has yet to pop the question, despite Perry's new accessory.
Check out more photos of Perry and Mayer's date night over at X17Online.
