Peter and Emily, who are parents to one-year-old daughter Amelia, are backing this year's World Cancer Day, which takes place tomorrow (4 February).
The Cancer Research UK initiative asks people to wear a Unity Band on their wrist to remember loved ones, celebrate survivors and support those going through treatment.
In December 2013, Peter lost his elder brother Andrew to cancer and he has been busy drumming up awareness for the charity ever since.
Following Andrew's tragic death, Peter set up the Peter Andre Foundation and Pete's Champions, both of which have raised money and support for Cancer Research UK.
Meanwhile, Peter and Emily aren't the only famous faces getting involved in World Cancer Day.
Pop band Little Mix, I'm A Celebrity...Get Me Out Of Here! hosts Ant and Dec and TOWIE's Lauren Pope are among a host of other celebrities who have been busy showing their support.
Pick up a Unity Band in Cancer Research UK shops. For more information visit cruk.org/worldcancerday
