Sophie Ellis-Bextor is planning a detox in January.

The singer - who has two children, Sonny, six, and 21-month-old Kit, with husband Richard Jones - never worries about overindulging over the festive season because she knows she will be taking it much easier the following month.

She said: "Relax and enjoy yourself. January's for abstaining and December is a time for fun."

The 31-year-old star has several parties to choose from to celebrate New Year's Eve (31.12.10) and is planning to fit in as many as she possibly can.

She explained: "I've been invited to three 'Mad Men'-themed parties. I'll try to get along to a couple and drink a lot of mulled wine."

Sophie has also revealed she is keen to have more children with The Feeling bassist Richard she doesn't plan to make 2011 the year she expands her family further.

She said: "I do want more kids, but not yet. Our youngest is only one so I want to give him a bit more time being a baby."
