Today there was a charity event where some Thai Stars were asked to contribute personal things which may be auctioned off for Charity (I think it had something to do with reforestation?) Bella gave the Padiwarada shirt which James and the other cast members signed during the last day showing (last episode) of Padiwarada and they were all watching it together.
Some people in instagram were saying the value of the shirt is 1) Bella wore it 2) James and other cast members of Padiwarada wrote on it (and James signed it while Bella was still wearing the shirt, mind you!) 3) It has James's saliva
here they are with their matching shirts. both signed respectively in the upper right chest. (photo cr on pic)
Thankfully, the lovely lady who won the bid, instead of keeping the shirt, said that she wants Bella to get it back. So she donated the money and gave back the shirt to Bella. I'm not sure if google translate is correct, but it seems James promised to personally return the shirt to Bella.
