The 22-year-old has penned a deal which will see him at the City Ground until 28 December and he will go straight into their squad for Saturday's Championship game with Huddersfield Town.
And the move means Ince will link up again with former Three Lions head coach Stuart Pearce, who gave him his Under-21s debut against Azerbaijan in 2012.
Ince, who has previously played on loan in Nottingham with Forest's city neighbours Notts County in 2010, signed a two year contract with Hull during the summer after leaving Blackpool, where he had become one of the Championship's brightest young stars with his performances on the wing.
He featured for the Tigers in the early stages of this season, scoring his first goal for the club in their League Cup defeat at Hull City.
Ince had previously featured for England at U17 and U19 level prior to that, after starting his career with Liverpool where his father Paul was a player in the late 1990s.
After helping England Under-21s qualify for next summer's Euro Finals earlier this month, Ince will be hopeful of being in Gareth Southgate's squad for the games with Portugal and France in November.
Tickets for the game at Turf Moor cost just £10 for adults and £5 for concessions. Call 01282 70003 for more details.
