Bent has had a mixed campaign so far with the striker dropping down the pecking order following the January arrival of Robbie Keane.
But the England international has re-established himself in Harry Redknapp's starting XI in recent weeks and scored his 15th goal of the season in last weekend's win at Aston Villa.
Jenas was delighted for Bent and was impressed by his overall performance against Villa.
"Apart from Darren's goal, his all-round work, hustling and bustling, winning headers, getting crosses in, chasing back, was magnificent at Aston Villa," said Jenas.
"He has come in for a lot of stick at some stages during the season and that just shows what tremendous strength of character he has got as well.
"I was delighted to see him score at Villa Park. He is a top striker. He is going to get you goals and that is what he is proving.
"I don't know many players that aren't confidence players. With strikers, goals breed confidence, games breed confidence. It is all part of football.
"Darren is having a little run in the team now and he is showing the manager exactly what he is about."
Below expectationsJenas admits Spurs have underperformed this season as they have found themselves battling against relegation rather than challenging higher up the league.
He continued: "If you look at our team, the players we have got, we really should be up there. We have been underperforming all year but in these last few months we have shown what we are really all about.
"There was a great performance in the Carling Cup final against Manchester United and we were very unlucky not to have lifted the trophy.
"We are in a good position at the moment but it is also important we focus on the fact we are not safe. It is a very tight league.
"But you don't go to places like Villa Park and get three points unless the whole team plays well. It was a great feeling all round on Sunday.
"That win will help fill the team with confidence for what lies ahead."
TargetMeanwhile, Adel Taarabt wants to use his loan spell with Queens Park Rangers as the springboard to launch his career with Tottenham.
The 19-year-old midfielder impressed on his full debut, in front of the watching Spurs boss Redknapp, as Rangers ran out 1-0 winners over Swansea on Tuesday night, and he is hoping to establish himself at White Hart Lane next term.
"Harry just told me to come here and make the most of it. That's what I'll do and I'll kick on after this," said Taarabt.
"I'm here for two months and it will help me. While I'm here we are going to try to make the play-offs. After that I will try to break through at Spurs but there is a lot of competition."
