A sun-like star orbiting a black hole
This strange system, called Gaia BH1, consists of a Sun-like star orbiting a tiny, massive object, which El-Badry and his colleagues say is black hole. If confirmed, this black hole would be the closest known black hole to Earth.The black holes were found by spotting the tiny wobble of its companion star while orbiting around it.

If you don't conside Jul 25, 2019 · The effect, a gravitational redshift, matched exactly what Einstein’s theories of special and general relativity predict. “The measurement of gravitational redshift around a supermassive black hole is really the beginning of a new era of testing general relativity,” said Lu, who began working with Ghez as a graduate student in 2003. A group of physicists has developed a model that charts the unexpected orbit of a star around a supermassive black hole, uncovering new insights into one of the cosmos’ most extreme environments. Millions of light-years away in a remote galaxy, a star is being torn apart by the immense gravitational pull of a supermassive black hole.

If you don't consider how the black hole (BH) has formed, then it is quite possible for a black hole to form a bound state with a massive object like a star. They can circle (or ellipse) around their center of mass (COM). If this COM lies close to the star then the BH will be orbiting around the star.
