She's never been known to smoke or drink alcohol.
But Jennifer Lopez was spotted puffing away on a cigarette Tuesday while playing a grieving mother on the Atlanta set of her film Lila & Eve.
As Eve Rafael, the 44-year-old pop star appeared to enjoy miming a tobacco habit between takes on location at a church.
In the drama - due out next year - the American Idol judge and Viola Davis play mothers whose sons have been gunned down in a drive-by shooting.
The distraught matriarchs then team up for avenge their sons' deaths after local authorities fail to serve justice.
Lila & Eve is directed by Charles Stone III, who helmed Crazy Sexy Cool: The TLC Story, Mr 3000, and Drumline.
However, the thrice-divorced diva appears to be a bit hesitant to tie the knot with the 26-year-old dancer-choreographer.
'I don't know, I don't know, we'll see,' Jennifer told reporters at an American Idol panel.
'I always believed in that institution. My parents were married for a very long time, for 35 years. I believe in it. It's difficult. I've had my challenges but at the same time I believe in love. That's the main thing.'
She added: 'I'm one of those people who does not like to be alone. I have no shame saying that at this point in my life. I think we have to own who we are.'
While in Georgia, Jennifer spent Saturday in an Atlanta recording studio working on her 10th album Same Girl.
Both singer Asia Bryant and Bad Boy rapper French Montana posted Instagrams from the studio with the I'm Real hitmaker.
The two-time Grammy nominee's new single - also called Same Girl - penned by Chris Brown is expected to drop any day now.
JLo can currently be seen on the 13th season of American Idol, airing Wednesday and Thursday nights on Fox.
