Sally Struthers was seen in public on Monday … weeks after her “All in the Family” costar Rob Reiner and his wife Michele were brutally murdered in their Brentwood home.

Sally was snapped out and about in Los Angeles … and her mood appeared to be glum … understandable given the recent double killings that rocked Hollywood.

TMZ broke the news … Rob and Michele were butchered in their home on Dec. 14 … and their son Nick has since been arrested and charged with their murders.

Among the countless fans and industry collaborators most recently paying their respects to Rob and Michele was Martin Scorsese … who penned an essay for the New York Times published on Christmas.

Martin said he bonded with Rob over being New York transplants in Hollywood and retold some jokes Rob made at various dinner parties over the years … and he praised Rob’s directing and acting skills.

“Owning Manhattan” star Chloe Tucker Caine says she swiped left on the man who would eventually become her husband several times … before her mom took over her dating apps.

The breakout reality star stopped by “TMZ Live” Monday and imparted a bit of wisdom for anyone in the market for a spouse.

Chloe told us … “A lot of times our parents see the best in us and they see a lot of times what we’re missing.”

But it took some serious convincing for Chloe to hand over the fate of her romantic life to her mother. Her mom persuaded her this was the way to go based on her own life experience. According to Chloe, her mother admitted to her that she picked someone based solely on looks … and didn’t want her daughter to suffer the same fate she did.

So this is how their little love operation worked … Chloe says her mom posed as her, essentially screening Chloe’s matches for her.

Chloe explained, “They didn’t know it was her. They thought they were talking to me!”

And even with all those dates lined up, she still wasn’t keen on meeting the man who would become her future husband. Chloe told us when her mom first showed her his pictures, she protested … “Absolutely not. He’s not my type. Never in a million years will I date this man.”

Now, they’ve been married for 5 years and are raising a 2-year-old.

“Southern Hospitality” star Grace Lilly was arrested Monday … after cops pulled her over and say they found a bottle of “happy pills” in her purse late Sunday night.

According to a police report, obtained by TMZ, Grace was driving through Charleston, South Carolina, in her Mercedes C-Class sedan with a man in her car. Officers say they initiated a traffic stop when Grace failed to use her turn signal to change lanes.

Cops say there was already a warrant out for her arrest in the system, so officers ordered her to step out of the vehicle and they detained her in handcuffs.

While detained, Grace allegedly asked if she could bring her purse with her to the detention center … and cops say they found a container of pills inside the bag labeled “Happy Pills.”

According to the police report, Grace said she had a prescription for the Xanax but did not have any proof at the time.

After booking Grace in the Al Cannon Detention Center, police say the pills were put into evidence to be tested for a possible drug violation.
