Border forces officers found the weapons when the WAG was asked to open their bag in a private jet terminal after a weekend, reports The Sun.
She is said to have told officials that she had bought the items overseas after a series of raids on the homes of football stars in the UK.
The illegal items were said to have been confiscated from the woman upon her return to the UK after she allegedly stated that she had nothing to report.
A source told The Sun: “When asked to open his bag, the police found illegal weapons. She immediately burst into tears.
“She seems to be very naively thinking that it would be OK to bring the stun gun to the UK to give her protection.
“She clearly had no idea that the possession of weapons like this is taken very seriously. “
Possession of a stun gun is punishable by up to six months in prison or a fine of up to £ 5,000.
Stretch batons are also illegal to carry, being considered as offensive weapons.

It is reported that the woman was not traveling with her footballer boyfriend, and it is unknown if she faces a penalty.
The Home Office, which manages the border force, is quoted by The Sun as saying, “We do not systematically comment on individual cases. “
Chelsea boss Frank Lampard and Tottenham midfielder Dele Alli are among the most prominent names who have recently had their homes targeted by criminals.
