The notoriously private couple arrived hand-in-hand to NBC Universal's star-studded afterparty, where they packed on the PDA at the Beverly Hilton Hotel on Sunday, Jan. 12.
The "Applause" singer and her Chicago Fire beau shared a passionate kiss as they entered the A-list soiree, appearing blissful as ever as they showed off their affection for another while paps snapped pics of the loved-up pair.
Gaga ditched her typical over-the-top style in favor of an elegant gold one-sleeved gown, although she still made sure to amp up the sex appeal as her dress was complete with a jewel-encrusted bustier and a thigh-high slit, which showed off the Mother Monster's enviable gams.
The 27-year-old beauty accessorized her sexy look with a pair of sky-high platform heels, delicate drop earrings and a large gold ring, wearing her long blond hair down in soft cascading curls.
Gaga's 32-year-old beau also looked handsome for the evening, donning a dark suit with a black shirt and bow tie while sporting his sexy stubble as he doted on his ladylove like a perfect gentleman.
The pop star most recently told Fashion magazine that she has "found love" with the handsome actor, although she admitted her road to romance hasn't always been easy.
"When you meet someone that's not intimidated by the amazing people that are around you [or] by the love that you receive—that's love," the Grammy winner told the magazine. "Men weren't always happy for me. It was very challenging to watch a woman be so successful."
Additional celebs in attendance at NBC's afterparty for the 71st annual ceremony included Ron Howard, Jesse Spencer, Michael J. Fox and wife Tracy Pollan, Amy Poehler, Jared Leto and Hayden Panettiere.
