The "Law & Order" star is one of the longest reoccurring actresses on the show since it first premiered and it brought her fame as well as the man of her dreams. The 56-year-old met her husband, Peter Hermann in 2002 while shooting the show's second season.

Their first date was at a church and this religious outing made Hargitay realize that she wanted to spend the rest of her life with Hermann. The lovebirds said their vows in 2004 at the Unitarian Historical Chapel and are now the proud parents of three children.

The hit show began in 1999 and continues to run 20 years later with its dramatic and suspense-filled episodes. According to Dick Wolf, the show's creator, "Law & Order: SVU" was initially meant to be called "Sex Crimes."

Wolf changed the name, so the show could be easily associated with its franchise and his work has earned him various awards over the years. Hargitay's role has also earned her several accolades and inspired her to create the Joyful Heart Foundation, which helped victims of domestic violence.

The show's executive producer, Warren Leight told sources that the 22nd season would be filled with many surprises and possibly the return of a famous cast member. The showrunner hoped to bring back Chris Meloni as Elliot Stabler but while his return was not certain, Leight shared details that were.

The new season will focus on the public's opinions about the police based on the real-life protests against racism and police brutality. There would also be special appearances by Riki Lindhome and Tamara Tunie.
