Cardiff Blues supporter Lucie, from Pentyrch near Cardiff, amazed judges and viewers of last year's X Factor with her renditions of Whitney Houston's 'I Will Always Love You'. She has since taken part in the UK-wide X Factor tour and signed a major modelling contract.
Lucie is now set to wow fans with a performance at the 27,000 seat Cardiff City Stadium on Sunday, ahead of kick off at 6.15pm.
Three teams have already qualified for the inaugural Magners League Play-Offs, Leinster, Ospreys and Glasgow Warriors, whilst three further teams, Munster, Cardiff Blues and Edinburgh are vying the fourth and final qualifying spot.
The atmosphere at the Cardiff City Stadium on Sunday is set to be electric, with the popular Cardiff Blues supporters villages set up for the game. There, fans will have the chance to meet the players for autographs and pictures, as well as a host of other activities.
Sunday will also see the launch of a new Cardiff Blues family membership, with a special area in the family stand. There will also be special offers on the day for season ticket renewals.
Robert Norster, Chief Executive of the Cardiff Blues, said: "This is a crucial game for the team, and we're hoping fans will get behind Cardiff Blues for a winning evening at the Cardiff City Stadium. The Supporters' Village has been well received at previous games, and with everything that's happening here on the day, combined with the anticipation of the game, the atmosphere is set to be fantastic."
