l saw an interview of will smith during the sharktale premiere on gmtv and he said that he has his children with him in italy.when the interviewer asked him whether he has all his three children he said that trey has started school that he only has the two younger ones.because trey is in school he cant travel as much with will as the smaller children because they are home schooled they dont go to a regular school like trey.l think we did not see trey during the i robot premiere because that time he was in italy studying italian.The last time l heard of trey was when someone posted on jada pinkett smiths wicked wisdom site that when jada and her band gave a free concert at the groove in august and will gave a surprise appearance the fan said she saw trey,willow and jaden sitted in the balcony and as will and jada were performing The fan said that all three children are very beautiful.And also trey and his mom sheree ,jada,will,willow,jaden and jadas mother attended wills sisters wedding in philly this july.
