They took their relationship to the next level over the weekend with a seaside proposal.

And Kourtney Kardashian had a chance to celebrate her recent engagement when she accompanied her fiancé Travis Barker to a concert from his friend Machine Gun Kelly at Los Angeles' Shrine Auditorium near the USC campus.

The 42-year-old Keeping Up With The Kardashians star held hands with Travis, 45, as they chatted with friends after the show.

As she often does since striking up a relationship with the punk rocker, Kourtney was attired in all black.

She had on a black leather jacket over a black black plunging blouse that highlighted her cleavage and had strings tied at the collar.

Even though the Kardashian–Jenner clan usually favors middle parts, Kourtney had her lustrous raven bob parted at the side and had delicate curls swept over one eye in a playful Veronica Lake–style peekaboo look.

Travis complemented her in a black tank top that showed off his tattooed arms, and he put on a studded black leather biker jacket covered in patches to ward against the cool night air.

The rapper-turned-singer (whose real name is Colson Baker) took to the stage in a gray ribbed short-sleeve sweater and graphic pants. 

He and Travis both favored the color pink for the show, with MGK rocking out on a pink electric guitar while the Blink-182 drummer pounded away at a hot pink drum set.

MGK showed himself to be a gracious performer, and he stopped during the show to chat with some fans, and he appeared to hand one of Travis' drumsticks to a young girl in the crowd sitting on someone's shoulders.
