Charlotte Church wants boyfriend Gavin Henson to prove his love for her by getting a tattoo.
The 'Crazy Chick' singer - who has one-year-old daughter Ruby with Gavin and is currently pregnant with the couple's second child - is reportedly worried her boyfriend will cheat on her because she has gained weight and wants him to show his commitment with an inking.
A source said: "Charlotte has been begging Gavin to get her name tattooed on him as she's still terrified he will stray. She has been designing tattoos that he could get done. She thinks that because they're not married he should do one special thing for her."
The singer - who previously said she wants to have six children - is so distraught about her appearance she has told Gavin she wants to get back into shape before they expand their brood again.
The source added to Closer magazine: "Charlotte has been pushed to her absolute limit with her weight gain. She told Gavin, 'I'm not doing this again! Plans for more kids are being put on hold after this one!' "
