Longmeadow actress Bridget Moynahan, who stars opposite Dorchester’s Donnie Wahlberg on the CBS cop show “Blue Bloods,” is doing her best to promote sales of this month’s Winston Flowers Charity in Blooom arrangement. Twenty percent of the proceeds from sales of the bouquet benefit the early education program Jumpstart, for which Moynahan is a spokeswoman. In case you can’t see it, the Jumpstart bouquet includes red hypericum berries and cotinus foliage. Winston tells us that this photo was taken as Moynahan left her New York City “Blue Bloods” set. . . . Speaking of Wahlberg, Donnie’s brother Mark is scheduled to participate in a live webcast with Men’s Fitness editor in chief Michael De Medeiros on Thursday at 5 p.m. The online event is sponsored by Wahlberg’s line of nutrition supplements, MARKED.
