The reality TV star has previously undergone the non-invasive cosmetic procedure - which involves having chemical injections in the face - and may have it done again because he admits he is vain and isn`t sure if he likes the wrinkles he`s getting.
The 38-year-old singer told Now magazine: "I can`t say I`m not vain because there are too many people who know me! I look after myself. I usually work out an hour a day at least four days a week. I wax my chest but I`ve never done crack, back and sack. And I`m thinking of Botoxagain. I haven`t had it done for two years and I can` decide whether I like my lines or not."
Peter - who was famed for his amazing abs during his pop fame in the 90s - also revealed he would like to do a fitness video to show people how to work out in a sensible way.
The `Behind Closed Doors` singer - who was previously married to Katie Price - said: "I`m not an exercise obsessive. I`d like to do a fitness video because I`ve never used steroids and I don`t overdo it."
