The Big Reunion 3T: 'The Jacksons don't tend to open up' - watch

The Big Reunion's 3T proved that they have a lot of work to do when Digital Spy met them - by forgetting their lyrics.

TJ Jackson was told off by his brothers when DS tested the trio on the lyrics to 'Anything' and he got the next line wrong.

"The worst part is, that's his line," Taryll Jackson joked.

Elsewhere, the trio explained that performing comes naturally to them but admitted that they've found it tough to open up about the highs and lows of their career.

"It's hard, because naturally we don't open up, and this show is all about opening up and letting people know your story," Taj Jackson said. "As Jacksons, you're kind of reserved. So that was kind of a hurdle for us."

The Big Reunion begins on Thursday (February 6) at 9pm on ITV2.
