Selena Gomez & Justin Bieber
A Hollywood date night was music to Justin Bieber
and Selena Gomez
's ears on Sunday.
The longtime lovebirds
made their way to the Living Room Lounge at the W Hollywood for the hotel's Sunday Jazz Series, taking in a performance by resident Brenna Whitaker and her Little Big Band, as well as child trumpet and tap dancing phenomenon, Gabriel Angelo, who appeared on Ellen DeGeneres
's talk show in April.
"Gabriel received a standing ovation from Justin and Selena," an onlooker tells PEOPLE of the couple, who "looked very much in love as they held hands at a front-row table."
According to the source, the lovey-dovey duo "left discreetly around midnight through a back exit." – Jennifer Garcia
