Tweddle trains with the City of Liverpool Gymnastics club
Beth Tweddle won the silver medal in the floor exercise at the women's European Championships in France.
Britain's Olympic medal hopeful lost out on the gold medal by 0.25 to 17-year-old Romanian Sandra Izbasa.
But the 23-year-old was unable to regain the uneven bars title as she came fourth behind Russia's 15-year-old world champion Ksenia Semenova.
Tweddle's ambitious new routine did not impress the judges, who were booed by the crowd for the marks they awarded.
The Liverpool athlete, Britain's only ever world gymnastics champion, won the bars title on 2006 but was unable to defend her title last year because of injury.
However, she was delighted with her success in the floor event.
"I was a late entrant into the competition because I've had injuries and I only started working on my floor routine two weeks ago," she said.
"It's always nice go home with a medal, whether it's on the bars or on the floor. It's nice to show I'm still up there on the floor and people can watch out for me later in the year at the Olympics."
