The 'Bad Romance' hitmaker, who got engaged to actor Taylor Kinney on Valentine's Day (14.02.15) after four years of dating, plans to serve her guests food from her parents' Italian restaurant in New York City, Joanne Trattoria, and wants her relatives to take key roles in her big day.

A source told Us Weekly magazine: "She's just coming up with ideas now.

"She's asked her sister Natali to be the maid of honour, and her dad can't wait to walk her down the aisle.

"They want it to be a family celebration."

The 28-year-old star, who is said to be eager to tie the knot at her $23 million mansion in Malibu, California later this year, has also started making her guest-list and plans to invite her good friend Sir Elton John, 67, to the event, as well as Tony Bennett.

The blonde singer - whose real name is Stefani Germanotta - released an album of duets, 'Cheek to Cheek,' with Tony last year and is said to have asked him to perform the title track at her reception.

Gaga recently revealed she started crying when 'Chicago Fire' star Taylor proposed.

She said: "First he gave me a Ring Pop. That was kind of amazing and I was crying, I was so excited.

'I said, 'Yes!' right away and then he pulled out the heart-shaped diamond. First it was candy. I was happy with the candy."
