But it wasn’t just singing siblings that were rising to prominence. Judy and Audrey Landers were known for being sisters and actresses. The Smothers Brothers were a comedic duo, and Virginia and Grace Kennedy were twins famous for having their own language. Read on to see how these siblings came to dominate the entertainment industry side-by-side.

The Osmonds were a group of male siblings who reached the height of their success in the early ’70s. Their sister, Marie Osmond, also became well-known for her career as a solo artist and for her duets with brother Danny.

Danny and Marie were so adored that they had a variety show that lasted until 1979. The siblings made a comeback in the ’80s, this time honing in on country music as opposed to soft rock. Donny and Marie ended up pursuing solo careers and even had a Vegas residency for over a decade in the 2000s.

Ann Wilson was the first to join the band Heart, which was at that point called White Heart. A few years after Ann became the lead vocalist, her sister, Nancy, joined in on guitar. The sisters must have been the missing ingredient because a year later the band rose to stardom.
