After three seasons of playing Dr. Jacqueline “Jack” Sloane on “NCIS,” Mario Bello bid farewell to the CBS series in March 2021.

She first appeared in Skeleton Crew, the 4th episode of NCIS Season 15, which aired on October 17, 2017. Her final episode was True Believer, the 8th episode of NCIS Season 18 that aired on March 2, 2021.

Measuring 5ft 5 (165.1 cm), Mario Bello was 50 years old when she first appeared on NCIS in October 2017 and 53 when her final episode aired in March 2021.

Maria Bello left NCIS due to the straightforward reason that her contract had expired, and she did not choose to renew it. Initially, her exit was planned to occur even earlier than it did, as she was contracted to appear from Season 15 through Season 17.

However, due to the COVID-19 pandemic and resulting filming disruptions, she stayed on to give her character, Jack Sloane, a proper exit in Season 18.

Bello’s departure from NCIS was entirely her decision, much like other actors who have left popular series to pursue other projects, such as Torrey DeVitto from Chicago Med.

She posted a heartfelt tribute to her Instagram, writing, “NCIS New Orleans ‘NCIS: New Orleans’ will end after Season 7 “And that’s a wrap for Jack Sloane @ncis_cbs !!! I’ve learned many things on this journey for the last three and a half years. I learned about commitment and community. I’ve learned that the woman I am enjoys process over product. I’ve never worked with a kinder, more generous group of people. I only had the privilege of standing by Dom’s side during cancer because my producers worked so hard to make sure I was there for every treatment. I made a speech today for our crew.”

“Though in our business, like many, there are quite a few assholes – there is not one on the set of NCIS – in front of or behind the camera. Only a profoundly decent group of people who care more about each other and the world in general than what is in it for them. I understand why this show after 18 years is the most watched in the world – you must all feel our love. Keep watching. I have a feeling there will be many more years to come. Thank you to all of my pals at NCIS and to all of our fans. I am truly grateful.”

After leaving NCIS, she was cast as Maria Bello as home improvement store owner Jordan in Lee Sung Jin’s American comedy-drama television series Beef.

With a net worth of $12 million, Maria Bello gained recognition for her role as Mrs. Smith in the television series “Mr. & Mrs. Smith,” despite the show being canceled after only eight weeks.

Bello subsequently appeared in the last three episodes of the third season of “ER” as pediatrician Dr. Anna Del Amico and later became a regular cast member during the show’s fourth season. From 2017 to 2021, she starred in “NCIS” and earned $125,000 per episode.

In July 2016, Maria Bello attended the 2016 American supernatural horror film Lights Out premiere at the TCL Chinese Theatre in Los Angeles.

She co-stars with Teresa Palmer and Alexander DiPersia in the supernatural horror film directed by David F. Sandberg.

The then-49-year-old American actress and writer sported a pair of harem pants from Greg Lauren’s (Ralph Lauren‘s nephew) Spring 2016 collection.

We imagine these pants would make M.C. Hammer proud.

Maria also wore a white spaghetti-strap tank top patterned with light blue geometric designs.

She accessorized with a chunky pyrite chain necklace, geometric earrings, bulky rings, and red lipstick.

She finished her black carpet outfit with a pair of delicate leather sandals by Alexa Wagner.

Maria’s lace-up “Kendra” sandals feature zigzag seaming along the slim straps and 3.75in / 95mm covered stiletto heel.

One month earlier, we spotted Maria Bello wearing an entirely different look to a special Hollywood gala celebrating women in film.

Rather than bulky mixed-media harem pants, she opted for a high-necked pink-and-white chiffon-style dress.

She wore her blonde hair down, kept her makeup simple, and ditched the bulky accessories.

She finished the ensemble with a pair of classic bubblegum pink pumps.

The hint of a red sole makes us assume these are Christian Louboutin shoes, but we can’t confirm. Any guesses?
