Karl Stefanovic poses with wife Jasmine, Alison Langdon and Brooke Boney at SMH anniversary event

On Thursday, Karl Stefanovic was flanked by three of the most important women in his life.

The Today co-host, 46, celebrated 190 years of the Sydney Morning Herald alongside his wife Jasmine, and colleagues Allison Langdon and Brooke Boney.

The father-of-four looked dapper in a dark suit for the occasion. 

Co-host Allison meanwhile also kept things elegantly simple in a high neck black dress.

The garment boasted a thigh high split that gave glimpses of the 41-year-old reporter’s toned legs. 

She capped off the monochromatic look with a pair a chunky white sneakers.

Allison was joined by her husband, Michael Willesee Jr, who looked dashing in an impeccably tailored suit. 

Today’s entertainment reporter Brooke Boney continued the theme with a black dress of her own.

The 33-year-old paired the garment with black heels and wore her wavy brunette tresses in a sharp bob.

Karl’s wife of four years Jasmine meanwhile donned a black dress with a plunging neckline, over the top of which she slipped a dark blazer. 

Former Australian treasurer Peter Costello was also in attendance on the night. 

The 63-year-old cut a suave figure in a navy suit, checked shirt and red tie as he posed on the blue carpet.
