Jennifer Lopez's work guilt

Apr 1, 2010, 6:03 GMT

Jennifer Lopez's children beg her not to go to work.

The 'Back-Up Plan' actress admits she is finding it difficult juggling her career with her home life now that Max and Emme - her two-year-old twins with husband Marc Anthony - are getting older.

She said: "They're at the point now where they've come to the door and started yelling, 'No, no, Mommy, don't go!' And I was like, 'Whoa, this is bad'.

"That's really tough. So I'm just going to have to figure it out as I go along. I keep trying to explain to them, 'I'll be home and the sun will still be out!'"

The 40-year-old singer-and-actress - who plays a woman who uses artificial insemination to get pregnant in 'The Back-Up Plan' also revealed she is unsure how she would cope without Marc's help and support.

She added to UsMagazine.com: "It's just too hard. Honestly. I have so much respect for single moms or anyone who finds themselves a single mother - but to choose to be a single parent is courageous. It's such a hard job to raise a child and to be everything to that child without a partner... I don't know if I could do it on my own, I really don't."

The couple had tried for a long time to conceive before learning they were expecting twins, and Jennifer says she and her husband had very different reactions when they were told they were having two babies.

She said: "I was in denial that I was even pregnant at first, so when I found out I was having twins, I just kind of laughed like, 'Of course this would happen!'. And then I started giggling.

"Marc started crying. It was a joyous time. We were happy... He's emotional! He just couldn't believe it was happening."
