It's Jennifer Lopez's 40th birthday! To celebrate, we turned to Astrology.com to get a special reading for Jen's big day. Plus, we give you the iVillage take on what this reading really means for J.Lo.

Sun Sextile Jupiter
Agreements, contracts, and joining your efforts with others will work out very much to your advantage now. A friend or person in authority may offer help or present an opportunity which will benefit you now or in the future. Also, you will reap rewards later for the generosity and aid you extend to others at this time.

iVillage Translation
If contracts will work to her advantage, it's a good thing husband Marc Anthony just bought a football team.

Sun Trine Moon
At this time you enjoy emotional satisfaction and harmony in your home life. Relationships with women run smoothly. If you have a solid emotional base in your life, you will receive the benefits of that. If not, this is a good time to begin making connections with people and also to discover what gives real emotional nourishment and fulfillment.

La Lopez recently told Extra, "I would love to have more kids. I don't know if we will. I don't know if that's in the cards for us. But we'll see." If there's harmony at home, perhaps today is the right time to start prepping for pregnancy.

Mars Square Mid-Heaven
At this time your efforts to get ahead and advance your own interests are likely to be met with resistance or animosity. You seem overeager, pushy, inconsiderate, or too narrowly focused on your own objectives, so that you alienate the people who could help you. Try to do as much as you can on your own, without trying to force others to agree with you or join you.

iVillage Translation
Jennifer better heed this advice. Recently her ex, Ben Affleck, spoke to this exact point. Of his relationship with Jen, he said, 'I was no longer in control of my life... I got lost. I felt suffocated, miserable and gross. I should never have gone down that route or got sucked in to all the publicity."

Sun Conjunct Sun
Today you want to stand out, to be the center of attention and receive recognition. It is a time to appreciate who you areas a unique individual. This is the beginning of a new year for you, and you feel charged with new energy, vitality, and sense of purpose.

iVillage Translation
This isn't just for today. Jenny From the Block always loves attention.
