Jennifer Lopez's twins Max and Emme enjoyed a fun-filled day at the Griffith Observatory in L.A. yesterday, and their famous mom must have been too busy to spend time with her little ones because they were accompanied by the nanny instead!

No wonder the Latina bombshell had to sit the field trip out! She's got a million things going on these days!

Not only is she preparing to drop a new album, she's also trying her hand at producing with the new ABC Family lesbian drama The Fosters, which she plans to guest star in sometime down the road.

"She was maybe thinking about doing a cameo in the pilot, but there was some apprehension in deciding how early they wanted to feature someone like her in the show. So she'll definitely come on, but at this point we just don't know when," show star Jake T. Austin told E! Online.

Lovely Miss Lopez works hard to provide for her tiny tots!
