The 'Lip Sync Battle' star felt like a "cool mom" after visiting Daniel Winter aka Winter Stone for a new inking, and showed off the results in a series of photos on her Instagram account.

In the first, Chrissy, 33, could be seen putting on a brave face while the work is being done, while the second picture featured a close-up of Daniel finishing off the piece.

In the final photo, Chrissy showed off her new ink, which has the dates of her father Ron Teigen Sr., mother Vilailuck Teigen, husband John Legend and their children Luna, three, and Miles, 16 months.

She captioned the gallery: "Cool mom back at it again with @winterstone!!!! (sic)"

Her 40-year-old husband joked she'd only had the tattoo to remember the important dates in her household.

He commented: "The ultimate mnemonic device!"

This isn't the first time the 'Bring the Funny' host has paid tribute to her family with a tattoo.

In April, she and John had matching cursive script on inscribed along the inside of their arms, with hers reading "John - Luna - Miles" and the 'All of Me' hitmaker's featuring "Chrissy - Luna - Miles."

Chrissy joked at the time: "Hey guys please don't talk to us unless u have tattoos we are a cool tattoo family now and we only want to talk to other tattoo families (srry if this seems harsh) (sic)".

The Sports Illustrated model also got a small heart tattoo on her index finger and she'd visited Daniel again for those inkings.

She wrote at the time: "Thank you thank you @winterstone. You are not only incredibly talented but you are very kind and delightful and welcome over any time!!(sic)"
