An eyewitness spotted Murgatroyd, 27, and Daugherty, 28, locking lips at a Los Angeles charity fundraising event, which included dinner and performances by Hollywood stars, on Sunday, Us Weeklyreported.
Murgatroyd was reportedly rubbing Daugherty's back at one point and they shared a kiss. They sat at a table together in the back of the ballroom inside the Hollywood Palladium, and according to the eyewitness, they subsequently kissed again a few times during the charity's raffle.
"Had so much fun at Trevor Live last night with this lovely lady by my side @petamurgatroyd," Daugherty captioned an Instagram photo on Monday of himself hugging Murgatroyd at the event.
The couple was reportedly inseparable all night and wasn't shy about showing affection for one another.
Rumors sparked Murgatroyd and Daugherty are dating last month when they kissed at the end of a Dancing with the Starsperformance and paparazzi caught them kissing in a parking lot leaving rehearsal. However, both parties denied they had interest in one another romantically, laughing it off and claiming they had no chemistry.
