The attacker delivered two standout performances to help Roy Hodgson's troops qualify for next summer's World Cup finals, scoring on his full debut against Montenegro last week.
But he found himself embroiled in a racism storm following Tuesday's victory over Poland after a dressing-room anecdote delivered by Hodgson at half-time was leaked to the media.
But Tottenham have sought to turn the focus back to the 22-year-old's flourishing career by confirming his new deal.
Spurs stated on their official website: "We are delighted to announce that Andros Townsend has signed a new four-year contract with the club."
Townsend posted on Twitter: "Delighted to have signed a new contract with spurs! The perfect end to the perfect week!! Now let's get 3points on Sunday."
Townsend has made eight Premier League appearances this season for Spurs after picking up valuable top-flight experience at QPR in the second half of the last campaign.
Prior to the 2013/14 season, Townsend had made 18 appearances for the White Hart Lane club, scoring three goals.
Spurs manager Andre Villas-Boas has no doubt Townsend will be able to shoulder the pressure of being England's next big thing.
Villas-Boas knows Townsend's every move will be scrutinised over the next seven months in the build-up to the World Cup, but he is sure the player will be able to cope.
"That is part of growing up as a player," said Villas-Boas. "I would suppose that wouldn't divert his attention too much.
"I expect him to be the same player. There are going to be more people worried about him, he will be more in the public eye and they will demand performances from him and I expect him to respond.
"Most of his colleagues are down to earth, he is in the right environment for his development and I think we have to help him in that sense."
Townsend had to go through nine loan spells before he got his first crack at regular first-team football with Spurs this season.
And the main reason the 22-year-old has had an extended run in the first team is because of an injury to Aaron Lennon, who is now fit and in contention for Sunday's game at Aston Villa.
Villas-Boas was concerned Townsend's experience with the international team would be counter-productive.
The Portuguese feared the winger would go down the same route as Jake Livermore and Tom Huddlestone, who received call-ups and were then quickly discarded.
Theo Walcott and Alex Oxlade-Chamberlain will come back into the reckoning by the time the World Cup comes around, but Villas-Boas is sure Townsend will feature for England for years to come.
He added: "We're very proud of what he has done, (we have) seen him play with so much confidence and determination he's really set his place in the team, for Tottenham and for his country.
"It's performances like this that keep your place in the team.
"Whenever he's been called up by myself or Roy he's given great performances.
"At the moment we're very happy with what he's been doing and I think Roy thinks the same.
"It's wonderful for him. He's come along with the explosion he had in the Premier League, not just with Tottenham but with his country.
"He is doing extremely well for club and country and deserves credit."
