Hollywood actor Michael Sheen , 007 star Sir Roger Moore and comedians Alan Carr , Lee Mack and Kevin Bridges are among the names who have put pencil to paper to create sketches for a good cause.
Llamau is holding its second Illustrating Homelessness charity auction with the help of stars of stage and screen.
The funds and awareness raised from the auction will help to shine a light on the vital work Llamau does with homeless young people and vulnerable women in Wales.
The famous names were all asked to draw a picture of their house and their piece of original artwork will be auctioned off at an evening of bidding at the home of Welsh rugby, The Principality Stadium, Cardiff.
