But in Kelly Brook's case, she revisits naked pin-up shoots.
The 34-year-old must have been feeling a bit misty-eyed over the weekend, as she celebrated flashback Friday with a memory from a 2009 photo shoot in Malibu.

Delighting her 280,000 plus followers, Kelly shared a snap of herself posing completely nude on a beach.
With her brunette tresses strategically tumbling over her assets to keep the shoot from descending into X-rated territory, the babe threw her head back while placing a hand on her shapely derriere.
With a leg bent slightly to preserve her modesty, a photo like this on, say, Rihanna's profile would have seen a swift deletion by the Instagram police – but Kelly appears to have dodged any discipline.
She even pretended that her photo was just a standard pic, not a teenage boy's dream, simply captioning the raunchy snap: "Malibu."
Continuing with the sun-soaked theme, Miss Brook went a bit selfie crazy this weekend as she documented her time in the sun.
Exposing her cleavage while lying down, Kelly claimed Kent was "heaven" – a bold statement, considering she spent her previous week in Jamaica.
The model flew to the holiday resort with fiancée David McIntosh for an engagement photo shoot, and if you thought the couple had mellowed out with their saccharine publicity seeking, you're sorely mistaken.
Kelly and Tornado gushed about their super-fast romance, which saw them getting engaged after just six months of dating.
Kelly said: "I think it took both of us by surprise, to be honest, how quickly things have progressed.
"But I've never met a guy like David before and although it seems soon to be planning our wedding, there's nothing to wait for in my mind because at the moment everything's fantastic and there's no reason why it can't continue to be like that."
The buxom beauty also divulged details about David's proposal.
She said: "I saw this beautiful diamond ring and I think my first reaction was, 'Are you sure?'
"He assured me he was, so I said 'Of course I will'. He slipped the ring on my finger and we kissed and it was just the most humbling, beautiful moment of my life. It was so genuine."
Genuine? We're sure Tornado-hater Chantelle Houghton – who labelled Kelly Brook "cringey" and "attention-seeking" in her latest column – will have something to say about that.
