Lake Bell has let her tattoo artist husband Scott Campbell ink her for the first time.

The 'Home Again' actress has been married to the 40-year-old inkman for six years and has finally let him near her with a needle, after which he described her as his ''favourite client ever''.

Scott posted a picture of Lake's new tat on Instagram and added the caption: ''After six years on the waiting list... finally sat down with my favorite client ever... @lakebell (sic)''

Lake - who has three-year-old daughter Nova and five-month-old son Ozzi with Scott - had matching patterned inkings on both of her shoulders.

While she has only just let her husband tattoo her, the expert - who has inked the likes of Sting, Robert Downey Jr., Justin Theroux, Orlando Bloom and Courtney Love - lets his wife have a go at putting some designs on his body whenever she ''really wants something''.

The 38-year-old star, who isn't a trained tattooist, recently said: ''He always jokes that his body is like the bathroom wall at CBGBs. He doesn't, like, delicately think about every tattoo.

''So the thing is, we have this way of praying, in a way, which is to send positive energy or juju out there, when we really, really want something - and we only use it when it's really important - he's like, 'Tattoo it on me.' ''

But Lake's designs haven't always been accurate.

The star revealed the first time she inked Scott she intended to write the word ''Sundance'' on his leg after she submitted her film 'In a World' to the Sundance Film Festival - but she misspelled the word.
