Somebody’s in a good mood.

Hunter Biden was grinning from ear to ear Thursday night as he joined first lady Jill Biden and his dad’s campaign co-chairman Jeffrey Katzenberg for dinner at celebrity hotspot Giorgio Baldi in Santa Monica, Calif.

The embattled first son, 53, showed not a care in the world hours after he finally agreed to sit down for a deposition in the House Republican impeachment inquiry of President Biden after months of defiance.

Katzenberg, the former chairman of Disney and onetime CEO of Dreamworks Animation, had just returned from sub-zero Iowa, where he touted Joe Biden’s campaign to counter-message focus on the Republican contest — bragging to MSNBC’s “Morning Joe” that “on the fundraising side, Joe Biden is kicking butt.”

Last year, the 73-year-old Katzenberg and his wife donated more than $1.7 million to the Biden Victory Fund joint fundraising committee.

The first lady, Hunter’s stepmother, joined the family dinner after appearing at a fundraiser Thursday afternoon in the northern California wine-country town of Healdsburg.

Secret Service and police lined the street outside the beach-adjacent Italian eatery while the family, including Hunter’s wife Melissa Cohen and toddler son Beau, dined inside.

Hunter had another tough week after his father’s Justice Department finally confirmed that his infamous “laptop from hell” is in fact real and matches iCloud backups — and not a “Russian plant” as his dad told voters during the 2020 election.

Prosecutors also revealed in a Delaware court filing Tuesday that cocaine was found on Hunter’s gun pouch in 2018 — which authorities say proves he’s guilty of felonies for buying and possessing a gun while addicted to drugs.

Hunter is battling federal charges on both coasts and appeared in a Los Angeles courtroom last week to plead not guilty to tax charges after allegedly failing to pay at least $1.4 million between 2016 and 2019.

A trial in that case is scheduled to begin June 20, right in the middle of Joe Biden’s re-election campaign.

The first son walked away from a probation-only plea deal in July over courtroom demands for assurances that he had broad immunity from liability for past conduct, including alleged violations of the Foreign Agents Registration Act, which could implicate his father.

House Republicans have assembled evidence that Joe Biden, as vice president, interacted with the foreign associates of Hunter and first brother James Biden — including those from China, Kazakhstan, Mexico, Russia and Ukraine — and accuse the Biden family of offering no tangible business services other than access to their powerful relative.
