Foote and her partner Giovanni Pernice earned three 10s for their Charleston, which they performed to Hot Honey Rag from Chicago.
Georgia and Giovanni dazzled with their Charleston
Despite a hitch in training, which saw Foote knocked in the back of the head during a lift, she went on to dazzle the judges, topping the leaderboard with 39 points.
Even the normally critical Craig Revel Horwood was bowled over, saying to the couple: "Three letters. L.U.V."
Head judge Len Goodman said: "Can I give you a little bit of advice? Take a coat to Blackpool because it gets very cold."
The Wanted's Jay McGuiness, who has been a favourite through the series, may be worrying about securing his place for next week after he stumbled slightly during his foxtrot with partner Aliona Vilani.
The judges have criticised him for not showing enough emotion on his face during his performances.
And on Saturday night, Revel Horwood pulled him up on the same point, saying: "I found the whole thing a little bland." He added "Your face goes dead, you've got to do something about that."
TV star Peter Andre, who topped the leader board last week, scored 34 points for his Viennese waltz to Cilla Black's 'You're My World'.
Call The Midwife's Helen George also ended up with the same score, with judge Bruno Tonioli calling her and Aljaz Skorjanec's Tango "slick".
He said: "That was a beautifully tailored, high fashion tango. It was slick, polished, you look like a supermodel in a Valentino dress. Kate Moss would have loved it."
After landing in last week's dance-off, EastEnders' Kellie Bright and Kevin Clifton performed a samba that earned them 33 points, as well as their first nine from Revel Horwood.
But the judges were divided in their opinion of the performance, which was performed to 'Boom Shake The Room' by Jazzy Jeff and the Fresh Prince.
Goodman told them: "The trouble is, I'm a cup of tea in a world of skinny lattes ... the two things I don't like is babies crying and hip hop. I admire your nerve and guts to come out and try something different and give it a go."
BBC Radio 2 presenter Jeremy Vine performed a quickstep to The Jam's 'Going Underground', with a mining theme.
His routine last week, which saw him dressed as a cowboy and started with him riding a plastic horse, went down well with the audience, but earned him 21 points.
This week Vine got the same score, with judge Darcey Bussell saying it was "a bit steady", but she thought it was "a great improvement".
Goodman couldn't resist a good play on words saying: "Excuse the pun but there were a few minor mistakes. I don't know who is going home tonight but what I do know is if you're not there (at Blackpool), there will be a lot of fun and entertainment missed."
Only eight couples will make it to next weekend's prestigious show, held at Blackpool Tower's Ballroom.
'Strictly Come Dancing' airs again this evening at 7.20pm on BBC One.
