Greg Biffle and his wife sent their holiday card in the mail before they died in a fatal plane crash … and the season’s greeting is just now showing up in mailboxes of relatives and friends.

One of Biffle’s friends, a restaurant owner in North Carolina named Ron Herbert, says he checked his mail Sunday and found a holiday card from the Biffles.

Herbert shared the card on social media … and it shows Greg, wife Cristina, his daughter Emma, and their son Ryder in matching outfits — blue jeans and white shirts — smiling and laughing in front of flocked Christmas trees.

Help is coming from all sides for “Ned’s Declassified” alum Tylor Chase … and now one of his former costars is stepping up, getting him a motel room to keep him off the streets, at least for the night.

Daniel Curtis Lee, who starred on the Nickelodeon series with Tylor, shared with TMZ an emotional video of him checking Tylor into a Riverside, California motel Tuesday … after driving about 50 miles from L.A. to meet up with his former costar, who’s been living on the streets.

Daniel tells TMZ … he spent part of the day with Tylor walking around and catching up over pizza before helping him settle into the motel so he could stay dry ahead of a major Southern California rainstorm this week.

As we reported … “Mighty Ducks” star Shaun Weiss also offered help, inviting Tylor to stay at a recovery facility he works with … but Daniel says Tylor has been reluctant to accept help involving hospitals or treatment centers, even after much encouragement.

Daniel says he sees immense potential in Tylor. For now, he says Tylor feels most comfortable living unhoused, and he hopes his friend pulls through.

Kamala Harris may be testing a post-politics pivot … swapping policy for pillow talk by dishing out advice to single women — and getting a little cheeky on the campaign trail of love!

The former VP dropped her relationship wisdom on the “Rich Little Brokegirls” podcast Tuesday … saying dating’s all about knowing your season, whether you’re voting for a wild Friday night situation or endorsing a wholesome Sunday-morning-coffee type deal.
