Steve Carell is sadly mourning the loss of his mother, Harriet Carell.

The 53-year-old actor took to Twitter yesterday to announce Harriet sadly died at age 90 on Saturday, May 7, just one day before Mother's Day.

"Harriet Theresa Carell. October 15, 1925 — May 7, 2016. Love You, Mom," Steve wrote on the micro-blogging site.

According to the [Associated Press](–People-Steve%20Carell-Mother/id-63c71f082528464abfac7e1bd12a6b9b)_, Harriet passed away in her Acton, Mass. home surrounded by family.
