I am not well. And yet I couldn\u2019t be more proud.\u201d<\/p>\n The mom of one marked the tot\u2019s first day of Pre-K on Tuesday, September 2, with a sweet sign commemorating the milestone moment.<\/p>\n \u201cI love the color green, my bunny Rosie, my family, ice cream and lollies, [and] Halloween,\u201d the sign read.<\/p>\n \u201cHis siblings hyped him up this morning as you can hear, and we all went to support his first morning drop off,\u201d Burgess\u2019 caption continued. \u201cMy blended tribe is my everything. We are so lucky.\u201d<\/p>\n Fox, 39, and Green, 52, began dating after meeting on the set of Hope & Faith<\/em> in 2004. They tied the knot in June 2010.
