Like father not like son, allegedly.

While the Hef-meister is a womanizer, he's also no brute.

He's the guy who puts his ladies on pedestals — monthly allowances, cars, and room-and-board reportedly included.

But baby Hef, Marston Hefner, not so much.

Cops say:

The 21-year-old son-of-Hef was arrested on suspicion of misdemeanor domestic violence last night.

The victim? TMZ says it's none other than 2011 Playmate of the Year Claire Sinclair. (Way to allegedly disrespect not only your GF, but dad's talent pool too).

The sheriff's inmate information database says Marston was arrested at 10:42 p.m. Sunday and released at 2:13 a.m. today based on $20,000 bail.

The incident happened at baby Hefner's residence in the 100 block of West Del Mar Boulevard in Pasadena, says local police Lt. Rick Aversano.

According to TMZ, “officers observed visible injuries in Sinclair's body, including bruises and red marks.''

Now the site says Sinclair has obtained a restraining order against Marston.

While we admire the junior Hef's ability to break with his father's tradition and go brunette, this hitting girls stuff is no good — if true.

Marston, make like daddy and throw money at them instead of fists, mkay?
