Sir Patrick Stewart’s widow Sunny Ozell has paid tribute to the Star Trek actor two weeks after his death at the age of 86, saying “the grief continues to come in waves”.

Sir Patrick died on October 28 following a “brief and poignant journey with Alzheimer’s disease and Lewy body dementia”, a statement on his social media said.

US singer-songwriter Ozell, who married the award-winning actor in 2013, has shared a touching tribute to her late husband on Instagram, saying they “left nothing unsaid”.

She wrote: “Today marks two weeks since Patrick passed, and the grief continues to come in waves.

“But I’ve also been experiencing such deep, profound gratitude. We left nothing unsaid.

“He knew I loved him, and I know he loved me.

“Patrick and I truly, authentically saw one another, and we amplified each other’s best qualities.

“We shared nearly two decades together, and we filled those years with so much living.”

Tributes have poured in from the acting and film world since Sir Patrick’s death, with Sir Ian McKellen, William Shatner, Dame Judi Dench and James McAvoy among those to mourn the star.

Ozell continued: “I’ve been overwhelmed by the public response to Patrick’s death, and while I’m not at all surprised that he touched so many, I’m sincerely moved by the outpouring of sadness and loss.

“Thank you all for your condolences, they mean so, so much to me.

“My heart had to grow to contain my love for Patrick, and he changed me for the better, forever.”

Ozell shared her tribute alongside a black and white photo of herself smiling as she embraced her husband, and her post sparked a flood of messages of condolence.

The couple first met in 2008 and finally tied the knot during an intimate ceremony five years later.

Sir Patrick was previously married to actress Sheila Falconer in the 1960s, with whom he had two children.

Sir Patrick rose to prominence as a member of the Royal Shakespeare Company in the 1960s.

He shot to international fame when he originated the role of Captain Jean-Luc Picard in Star Trek: The Next Generation in 1987.

The sci-fi TV series ran for seven years, with films Star Trek Generations in 1994 and Star Trek: First Contact in 1996.

Sir Patrick was also known as the Marvel superhero Professor Charles Xavier in the first three X-Men blockbusters, which began life in 2000.
