Jennifer Lopez and boyfriend Casper Smart could be headed for a breakup after they haven't been photographed together in the last few weeks, according to reports. 

Radar Online pointed out that when the American Idol judge appeared in Washington D.C. on Oct. 5 to take home the Ally for Equality Award, she happily walked on the red carpet and posed for pictures with guests. To a surprise, she was not accompanied by Smart.

According to sources that confirmed to the celebrity news site, the couple is headed for splitsville and broke up briefly over the summer. 

Even during a photoshoot for Viva Movil in NYC on June 14, a source said, "Everyone on set was whispering about the news that J.Lo and Casper broke up."

"She seemed down and looked tired, like she hadn't slept well. She holed up in her trailer for hours when she wasn't needed for her scenes, and asked for vanilla Haagen Dazs ice cream and white flowers. It was obvious she was a million miles away."

At the time, Smart posted Instagram photos of a solo camping trip. 

"Jennifer's team started scheduling all her major appearances solo," the source said.

The source added that the couple is simply at two separate points in their lives. 

"They're obviously in very different places in their lives, and Jennifer wants to take responsibility for her life and not repeat the same mistake she has made in the past. She enjoyed the relationship for what it is, but now that giddiness has turned to sadness."

The couple reportedly was last seen together on Sept. 21.
