A Nicky Hilton Citing

Nicky Hilton followed in her big sister Paris' footsteps and got pulled over by the police in L.A. yesterday ... but the only thing she was under the influence of was a cell phone. 

Law enforcement sources tell us Nicky was ticketed for driving while talking on her cell phone. In California, drivers are required to use a hands-free device.

The fine usually runs somewhere north of $100 ... thank god she can afford it.
