Red Nose Day: The highlights so far

Last year's Comic Relief efforts managed to raise a whopping £74.3 million, and this year shows no signs of slowing down.

Radio 1 DJ Nick Grimshaw has dyed his hair pink, Miranda Hart has been completing a Mad March challenge each day this week in different cities, and Peter Kay has forced himself to sit down for practically a whole week.

In the office today, we've seen people in their PJs, a cycling competition, and cake and book stalls.

Unfortunately the JustGiving fundraising site crashed earlier, but it's working normally again now.

Tonight, we can expect to see a performance from One Direction, Jessie J shave her head and best of all, Will Ferrell will appear as Anchorman Ron Burgundy in a one-off sketch recorded especially for Red Nose Day.
