She’s the youngest child of one of America’s most iconic crooners, born during the first of his four marriages.
And while both her brother and sister found some fame in the swinging ’60s this daughter chose a quieter path.
She did dip her toes in her family’s specialty, joining them for a 1968 Christmas album, lending her voice alongside her famous father and siblings.
But rather than chase the spotlight, she found her strength behind the scenes, carving out a successful career as a theatrical agent.
When her legendary father passed, she stepped in once more – this time to protect and preserve his cinematic and musical legacy.
Can you guess who she is?

The younger daughter of a true music legend was spotted out and about in Los Angeles the day before she turned 77

It’s Tina Sinatra!
Tina was spotted on Thursday talking a stroll before stopping to chat with a gardener a day before her 77th birthday.
Wearing a bright purple strappy maxi dress with a floral print, she bent down at one point to smell a rose.
As she bent down, a floral tattoo was spotted, centered on her back between her shoulder blades. Another one was visible on her foot.
Her sister Nancy’s silky transatlantic tone and striking style made her a household name primarily through the novelty hit These Boots Are Made For Walkin’ which was a Number One hit throughout the world in 1965.
And Nancy, now 85, teamed up with her famous father for Somethin’ Stupid, which was also a huge international hit the following year.

Even at a young age Tina realized she did not have the confidence to be a performer. While sister Nancy and rother Frank played the piano watched by their mother, she stood back

Tina’s brother, Frank Jr. – who died in 2016 aged 72 – had less success, but was still a regular guest on TV.
Frank Jr. is best remembered for being kidnapped from a Lake Tahoe hotel room in 1963 when he was 19.
His father eventually paid over $240,000 and he was released unharmed after two days. The two kidnappers were sentenced to long prison terms but only served a fraction of them before they were freed.
But twice-married, twice-divorced Tina largely kept out of the limelight. She did a little television work in Germany where she lived for several years and appeared in a few episodes of TV shows in the States including It Takes a Thief and McCloud.
She worked behind the scenes as an agent and film producer and in her 2000 memoir My Father’s Daughter she wrote that she ‘lacked the ambition and confidence’ to become an actress.
Oscar-winning director Martin Scorsese has long been planning a biopic of Tina’s dad, who died in 1998, but it has been hung up by disputes with Tina who controls the Sinatra estate.

Frank Jr. and Nancy both obtained their own fame which Tina did not seek. They appeared together on The Smothers Brothers Comedy Hour in 1968
Kevin Spacey and Leonardo DiCaprio have both been named as possible portrayers of Ol’ Blue Eyes with Jennifer Lawrence at one time named in the role of actress Ava Gardner with whom the legendary crooner had an affair that ended his marriage to Tina’s mom, Nancy Barbato.
‘They won’t agree to it,’ Scorsese told the Toronto Sun last year, referring to the surviving Sinatras.
‘Open it up again and I’m there!’
Shortly after that interview, Tina disputed Scorsese’s account. ‘Marty and I have been dance partners for a long time and not once has he stepped on my toes!’ she told TMZ.
But still there was no movement and the movie, which would look at Sinatra’s alleged mob connections as well as his philandering is no closer to being made than it was in 2009 when Scorsese first floated the idea.
Sinatra was married three times – to Barbato from 1939-51, to Gardner from 1951-57 to Mia Farrow from 1966-68 and to Barbara Marx from 1976 till his death.
He was also engaged to both Lauren Bacall and Juliet Prowse and had numerous affairs, including with Marilyn Monroe and Lana Turner, giving Scorsese plenty of material for his movie.
The Hoboken, New Jersey, native was also dogged throughout his life by allegations of Mafia ties. He even admitted that if he hadn’t have fallen into showbiz he would probably have lived a life of crime.
The FBI kept him under surveillance for more than 50 years.
