Tiffani Thiessen looks somber following the death of Saved by the Bell co-star Dustin Diamond

Tiffani Thiessen looked somber as she stepped out following the death of her Saved by the Bell co-star Dustin Diamond.

The 47-year-old actress was spotted picking up a cup of coffee in Los Angeles shortly after news broke that Dustin lost his battle with cancer on Monday.

Diamond, 44, died just three weeks after being diagnosed with stage four small-cell lung carcinoma. 

Tiffani kept her eyes on her cellphone as she made her way to a local coffee shop wearing a grey T-shirt, black coat and slacks.

She abided by local regulations requiring a face mask while outside of the home due to the COVID-19 pandemic and sported a colorful covering between sips.

Thiessen was joined by her husband, Brady Smith, who was on dog duty as he walked by her side.

After hearing of his death, Tiffani joined the legions of friends, fans and former co-stars in honoring the comedian.

‘I am deeply saddened by the news of my old co-star @realdustindiamond passing,’ she wrote. ‘Life is extremely fragile and it’s something we should never take for granted. God speed Dustin.’ 

Diamond was cast as nerdy Samuel ‘Screech’ Powers on Saved by the Bell when he was just 11 year old, a role he played for 13 years through various installments of the popular teen sitcom.

Dustin reportedly had a large lump on his neck before he died and was hesitant about having it seen by a doctor for fear of attracting public attention. 

Diamond’s girlfriend, Tash Jules, 39, exclusively told DailyMail.com, ‘He was the love of my life. We planned on a future together and spoke often about having kids. I’m heartbroken.’ 

Tash, a certified pharmacy technician, said she is devastated and her entire world has been turned upside down. But she said she will cherish the last time he was able to speak to her – just one day before he died.

‘Even though he was struggling to breathe and had difficulty speaking he was able to get out the words to me, ”I love you,” I told him I loved him back.’

Tash said, ‘Dustin died at our friend Jules’ house in the Fort Meyers, Florida area.’

He had been hospitalized since last Friday and had just been released around noon on Monday, and was being taken to their friend’s house by medical personal for hospice care.
