Make-up free mother Jennifer Lopez spends time with her twins Max and Emme during dance rehearsals with Casper Smart

For the last few months she has been busy with her American Idol hosting duties, promoting her new album and getting ready for her world tour. 
But yesterday, Jennifer Lopez took time out from her hectic schedule to be with her four-year-old twins, Max and Emme.
The 42-year-old make-up free star was taking a break from a dance rehearsal with boyfriend Casper Smart as they prepare for their anticipated tour.

Motherly duties: Jennifer Lopez took a break from dance rehearsals to spend time with her twins Max and Emme yesterday

The rehearsal took place on the same day that would have been her's and former hubby, Marc Anthony's, wedding anniversary.
Wearing a white vest and some red tracksuit pants, J-Lo was the most casual she has been seen for the last few weeks.
Gone was her usually glam attire and hairstyles, and in place was almost the J-Lo of old from her Jenny From The Block days.

Natural state: The 42-year-old had no make-up on her complexion and wore some cosy red tracksuit pants and a white vest

The singer wore her hair swept back in a casual bun and had simple gold hoops in her ears.
Meanwhile, Max and Emme were both tended to by nannies.
While Max carried his iPad and hopped into the back of the SUV, Emme was sound asleep in the arms of another caretaker.
Jennifer later slipped on a black tracksuit top and some sunglasses as the entire family were shuttled home.

Beau: Jennifer was joined by her much younger boyfriend Casper Smart

It was the second day J-Lo's children were seen on set with their mother.
Last week the Latina lovely was spotted wearing baggy metallic trousers for dance practice and her beau Casper was larking around with a feather headdress.
Quite what Jenny From The Block was making of her much younger boyfriend's fascination with the flamboyant red accessory is anyone's guess.
But the 24-year-old looked far from macho, even as he tried to strike a manly pose by clenching his fist and grimacing for the camera.

He even waved it at his lady friend as he gamely tried to win her approval.
The Love Don't Cost a Thing star looked delightfully sweaty as she worked on her moves ahead of her upcoming world tour.
And she certainly seemed to be having a good time as she hopped around in her spangly trousers, which she twinned with a grey vest, purple trousers and blue sports bra.
Jennifer and Marc are currently sharing custody of their children.

Recently, the actress/singer asked a judge for permission to take her children on tour.
J-Lo will embark on a series of concerts with Enrique Iglesias this year, but could face legal problems with Max and Emme accompanying her.
After her fellow performer and father of her children, Anthony, filed for divorce in April, a court ordered that their offspring should not cross the border of California without prior permission.

Now Jennifer and 43-year-old Marc will both be outside of the state as he kicks of his own gig dates in August, according to TMZ.
The What To Expect When You're Expecting star has filed documents asking for and her estranged husband to arrange shared custody schedule for the duration of them being away from home between themselves.
However the parents won't find out the court's decision until briefly before they are due to travel.
A court hearing has been arranged for June 26 and Jennifer's tour with Enrique begins in July.
