Blake Lively might want to look over the food handler’s license test … ’cause her free-flowing locks have put a Connecticut donut shop she helped out under a microscope.

Here’s the deal … earlier this week, Lively helped out a friend who owns a small donut shop in Wilton, CT — working a mixer, putting out the sweet treats for customers and just generally doing down-to-earth, everyday kind of work.

Of course, some people online have a bone to pick with Lively … and, they’re pissed she didn’t put on a hair net or a hat, or tie it back, while working and serving up the treats — writing on social media about it, even calling the local health department.

Worth noting … the shop’s Yelp Page has been temporarily disabled because commenters flooded it with negative reviews after Blake made her cameo appearance there — with Yelp explaining they’re investigating “whether the content you see here reflects actual consumer experiences rather than the recent events.”

Before comments were disabled, a few users did actually post about Blake’s lack of a hair net … so, it seems it was something people really noticed this time around.

While some may actually be mad about hair nets, it’s safe to assume some are just happy to hate on Blake because of her legal battle with Justin Baldoni.

A source close to Blake tells us … “The so-called complaints are from people who have never been there and who don’t even live in Connecticut. Targeting a lovely, small, family-owned business is a new low in the retaliation campaign.”

Blake’s haters called her a hypocrite just this week for a resurfaced interview where she admitted to improvising a scene where she grabbed her costar Henry Golding‘s balls during “A Simple Favor.”

Only time will tell if the Wilton Health Department’s investigation will prove sweet — or if it’s really just full of holes.

A new trailer for “Superman” has dropped … and, it’s giving fans a longer look at Krypto the Superdog — and, a peek inside the Fortress of Solitude.

The new clip — which runs about five minutes long — came out Thursday, and while it features much of the same footage from the trailer that was dropped in December, it’s got a whole lot of new content too.

Check out the clip … the first three and a half minutes features an extended look at the original trailer’s opening scene where Superman, played by David Corenswet, calls on his dog Krypto to save him.

Warner Bros is making a major marketing push with this trailer BTW … ’cause it’s supposed to play before every screening of “A Minecraft Movie.”

Kim Delaney looks like she’s smoothed things over with her husband … loving on him for his birthday a few days after he told cops she tried to use her car to hurt him.

The former “NYPD Blue” star got her hubby, James Morgan, a bouquet of flowers Thursday for his 55th birthday.

Kim proudly showed off the gift with a social media post … saying, “Birthday Boy, 55!!!!! Your wife loves you, my guy!” She also added a song, Chris Stapleton‘s “Joy of My Life.”

Police say James left their home after Friday’s alleged incident and returned Saturday morning … prompting Kim to call the cops again. Sheriffs deputies responded and say James told them Kim tried to hit him with her car and showed them video of her alleged attack.

Kim appeared in court Tuesday morning and prosecutors declined to file charges against her or her husband.
