3T made a vow to help raise their uncle Michael Jackson's children after he died.
The three band members Taj Jackson, Taryll Jackson and TJ Jackson are Michael's nephews and after his shock passing in June 2009 they all told their grandmother Katherine Jackson they would always be there for his kids, Prince Michael, 16, Paris, 15, and 11-year-old Blanket.
During an appearance on UK TV show 'Lorraine', TJ said: "Since my uncle passed - we lost our mother at young ages too - and that's a very hard thing to get over so when my uncle passed, my brothers and I, we told our grandmother we'll be there for her and do everything we can to help her and the kids. It's been hard, it's been tough, this is why it's taken us so long to come out [into the spotlight again] as well because our focus has been them, to make sure they're back on track and adjusting as best as they can. They're doing really well ... it's a hard position they're in but they're doing well."
3T - whose father is Michael's brother Tito - are currently featuring on TV show 'The Big Reunion', which shows them making a new bid for pop success.
The 'Anything' hitmakers are delighted to have been given another opportunity to perform together again.
Tarryll said: "It was just more politics and things that prevented us to continue our career ... A lot has happened since the last time we were on stage."
TJ - who is co-guardian to Michael's children - said: "Things in life got in the way so we went back to make sure our lives were in order before we continued our career."

Ant and Dec think fatherhood has made Simon Cowell softer like their pal Robbie Williams.
The 54-year-old music mogul welcomed his first child, Eric, last week and the presenting duo - who front Simon's show 'Britain's Got Talent' - feel the star will change like Robbie, who has a 17-month-old daughter, Theodora Rose.
Ant told The Sun newspaper: "I texted Simon and he texted back saying he can't wait for us to meet him.
"It's going to change him. I've seen the change in Rob since he's had Teddy. It changes you for the better.
"Rob is just gushing about it all the time. I hope the same thing happens to Simon. I'm sure it will."
Dec then added: "I don't think Simon expected to fall in love with Eric so instantly. I don't think he knew how much it was going to change him."
The stars also revealed they are working on a sitcom to celebrate their 25 years working together on TV.
Dec said: "It will probably be based on two guys who are mates who happen to present Saturday night TV shows and live together and the hilarious capers that follow. There would be good material in that."

James 'Arg' Argent cheated on Lydia Bright with Amy Childs.
'The Only Way Is Essex' star and his ex-girlfriend split up two years ago over cheating claims and Lydia, 22, quit the ITV2 reality show last year to focus on her fashion career.
Speaking at the launch of the new series of 'TOWIE', which starts on Sunday (23.02.14), Arg, 26, admitted he'd been unfaithful with friend Amy.
He said: "I've never revealed this before but I actually cheated on Lydia with Amy Childs. It was in the toilets at an ITV party. Sam Faiers walked in on us.
"It happened when I was with Lydia. I didn't sleep with Amy but we kissed and I got caught."
Arg is also set to reveal more juicy details about his love life in his new autobiography 'Living It Arg', out next month.
Asked if Amy, 23, knew that she would feature in his book, he said: "Well, she has tried to call me a few times."
Meanwhile, Arg's love life appears to be back on track and he has been sending flirty text messages to a London girl who he met in Ibiza 18 months ago.
He added: "Last week she texted me from New Zealand and said: 'Will you be my Valentine?' We'll see what happens."
Despite the heartbreak, Lydia has no regrets about falling for Arg in the beginning, saying: "I believe everything you go through in life happens for a reason and you have to learn from your mistakes.
"If I hadn't got together with James, I probably wouldn't have been introduced to 'TOWIE'."
'TOWIE' is back on ITV2 on Sunday at 10pm.

Jack Whitehall has been banned from talking about his girlfriend on his stand-up comedy tour.
The 25-year-old comedian, who is dating his 'Fresh Meat' co-star Gemma Chan, has revealed the actress doesn't want details of their relationship to be included in his stand-up routines in order to keep their romance private.
Appearing on tomorrow night's (22.02.14) episode of 'The Jonathan Ross Show', Jack said: "She doesn't want me to talk about it. And our relationship is the one thing that one tries to keep sacred so that's why I don't really talk about it that much. I don't talk about it that much, I make the odd silly joke [but] I try not to go into too much detail. It's nice to keep something back."
But the star couldn't help but gush over his stunning girlfriend, adding: "She's a lovely, amazing human being and I'm very, very lucky to be with her. That was soppy, wasn't it?"
Jack also stars in BBC Three's 'Bad Education', which he created, and he reveals he is in the midst of writing new episodes.
He said: "I'm writing some more as we speak. We're going to be filming in the summer."
In addition to 'Fresh Meat' and 'Bad Education', the comic could soon be snapped up by TV bosses in America as he recently filmed a pilot for a sitcom in the US.
He explained: "I filmed a pilot in America and now some other people will decide whether they want more. It was fun, it was different ... it's always weird doing things in America and adjusting to it."

Gareth Gates found last night's episode of 'The Big Reunion' "hard to watch".
The former 'Pop Idol' runner-up has formed new super-group 5th Story with Another Level's Dane Bowers, Adam Rickitt, Kavana and Blazin' Squad's Kenzie, and he admits it was difficult reliving his pop star past, including his brief relationship with Katie Price at the age of 17.

Dane tweeted: "I do miss Another Level...but @WeAre5thStory is something I'm LOVING too!! We are seriously gonna have a good chance... (sic)"
And responding to his band mates' own dramatic stories - including Gareth's fling with Katie and Kavana's past rivalry with Adam - Dane wrote: "Well you definitely can't call @weare5thstory boring that's for sure!! (sic)"

Snooki is having a 'Great Gatsby'-themed wedding.
The reality TV star - real name Nicole Polizzi - is getting ready to tie the knot with her fiancé Jionni LaValle and has chosen the theme for her nuptials, which will be based around the F. Scott Fitzgerald novel set in the roaring 20s - which was recently turned into a film by Baz Luhrmann.
She told In Touch Weekly magazine: "It's a 'Great Gatsby' theme, with black and gold."

She revealed: "I got my dresses. Everyone expects me to wear glitter and leopard [print] and I'm like, 'Maybe, if I got married four years ago'. I got an elegant ballgown for the church, and a mermaid style dress with a poufy train for the reception."
Although she wants her big day to be special, Snooki is not going to spend a fortune on her wedding and is going to cut costs where she can.
She said: "I don't have a wedding planner. I'm trying to save money - I'm so cheap! Plus, I don't like people telling me what to do."

Lana Del Rey's new album 'Ultraviolence' is being produced by The Black Keys' Dan Auerbach.
The 'National Anthem' singer took to Twitter yesterday to post a picture of herself sitting on the lap of the rock frontman and Grammy Award winning producer.
She teased fans by writing alongside the snap: "Me and Dan Auerbach are excited to present you Ultraviolence."
Dan has produced records for a number of artists including The Growlers, Hanni El Khatib and Dr John, and the picture hints that he has been working with Lana on the follow-up to 'Born to Die' in 2012, her second studio album.
'Ultraviolence' is rumoured to be released on May 1, after the singer accidentally told a fan the release date, whilst signing an autograph.
Speaking about the new record, she also said: "It's so good that it made me forget about the last record. I'm in love with it. I have that romantic feeling about it."
The 27-year-old singer revealed the title of her next record at the launch event for her short film Tropico last year. Appearing onstage at Hollywood's Cinerama Dome, she said: "I really just wanted us all to be together so I could visually close the chapter before I release my new album, 'Ultraviolence'."
Last month she also released new track 'Once Upon A Dream', the theme song from the soundtrack to the new Disney film, 'Maleficient'.

50 Cent will release his next album on an indie label.
The 'Candy Shop' hitmaker has severed ties with Eminem's Interscope imprint, Shady Records, after 12 years and will now be working with Caroline, a music distributor owned by Universal, starting with his album 'Animal Ambition', which is due out on June 3.
In a statement, the star said: "I recorded so many album quality songs that I'm going to put the Animal project out as my viral marketing plan and then [Street King] will come out after. [Animal Ambition] is about prosperity ... ambition and prosperity."
The 38-year-old rapper has sold millions of albums for Interscope, including 15-million copies of his debut record, but the star's relationship with the label has been difficult since 2009's 'Before I Self Destruct', which failed to conquer the charts.
Its follow-up was delayed and the rapper complained on Twitter and threatened to leak an unreleased Dr Dre song. But despite the problems, 50 Cent insists he still owes Interscope one album and Eminem has wished his former protégé well, saying: "Shady simply would not be what it is without 50 Cent.
"I've developed a great friendship with 50 over the years, and that's not going to change."
His move to an indie label is similar to the arrangement used by Macklemore and Ryan Lewis for 'The Heist', and Pet Shop Boys' scheme for last year's 'Electric' LP.
The rapper added: "I have had great success to date with Shady/Aftermath/Interscope, and I'd like to thank Eminem and Dr Dre for giving me an incredible opportunity.
"I've learned so much from them through the years. I am excited to enter this new era where I can carry out my creative vision."
50 Cent's last UK hit was the 2012 single 'My Life', which peaked at number two at on the UK Single's Chart.

Britain's Prince Harry has reportedly given Cressida Bonas free-rein of Buckingham Palace.
The 30-year-old royal has been dating the blonde beauty for just over a year and has now decided to take their relationship to the next level by allowing her to enter the palace grounds without being searched.
A source told Grazia magazine: "Cressida has been staying with Harry pretty much every night for the last few weeks. So Harry felt it was sensible that she got the security clearance to come and go as she pleases, instead of always having to enter with him.
"She's now on first name terms with all the security guards, and uses all three entrances to the palace."
Sources claimed last year the pair's relationship was heading for the rocks following reports of Prince Harry planning to pop the question, but friends close to Cressida, 24, insist they're loved-up.
The friend explained: "Cressida had a wobble just after Christmas. The speculation about whether they would get married had become too much and she declined an invitation to Sandringham to join the royal family on a shoot. Instead she flew to Necker Island to be with her half-sister Isabella and brother-in-law Sam Branson.
"Cressy just needed breathing space. Harry has been brilliant and understands completely. The fact she has now been given free access to the palace is all a part of his plan to ease her into royal life and prove she can still have a normal life as his girlfriend. She hasn't fully moved in yet, but she stays most nights."
