Teresa Giudice’s family has got generosity on lockdown.

The “Real Housewives of New Jersey” star, who served an 11-month prison sentence for fraud, was dining with her reality star brother Joe Gorga and his wife on Saturday when he made a Weehawken waiter’s week.

A fellow diner dished that Gorga tipped the server $500, which “brought tears to his eyes.” The waiter told Page Six that “It’s nice to see a reward for your effort. I haven’t figured out yet [what to do with the money]. I have two kids I support and I am sure they will find a good use [for it].”

Here’s five other celebs whose generous tips have become the stuff of legend.

  • He’s got 99 problems, but tipping ain’t one. Jay-Z’s 2011 “Watch the Throne” release party was a win for everyone working at Miami’s Fountainebleau, since he left a $50,000 gratuity – an average American’s salary – on $250,000 of champagne.
  • No joke: Last year Amy Schumer left the bartenders working Broadway’s “Hamilton” at the Richard Rodgers Theatre a $1,000 tip on a $77 tab. She also gave a Long Island waitress $500 on a $50 bill in 2015 after learning the server was working two jobs to pay for college.
  • Johnny Depp tipped a waiter at Gibsons steakhouse in Chicago $4,000 in 2009 after the server accommodated the “Pirates of the Caribbean” star and his party; they’d arrived after 11:30 p.m. and requested a private room.
  • There’s no bad blood here. Taylor Swift, Ed Sheehan and Austin Mahone shared the love at Philly restaurant Ralph’s in 2013, posing for pix with fans and even mugging for a shot for the eatery’s Facebook page. That was just the tip of the iceberg. Swift also left a $500 tip on her bill, and better yet, gave the head chef two tickets to the show the next night for him and his son.
  • Jessica Simpson personalizes her gifts, such as the generous $300 tip she left a Lavo waitress in NYC in 2011. Besides giving 60% gratuity on the $500 check, Simpson wrote her server a thank you note that said, “You were amazing and make this world a better place. Love, Jess.” Priceless.
