Sounds like Taylor Swift—but, in fact, it’s her frequent competitor, Katy Perry. Largely because of her Prismatic World Tour, which is now winding down, Perry pulled in $135 million this year. She grossed more than $2 million per city over the course of 126 shows in our scoring period, and added to her total through deals with Coty, Claire’s and Covergirl.
In an industry enthralled to rehashed stories that strike a familiar chord with audiences, give Pixar credit for often trying something new and pushing their viewers into uncharted territories. Coco, directed by Toy Story 3’s Lee Unkrich, has a visual look based around Mexico’s Dia de los Muertos (Day of the Dead). It’s about a young boy named Miguel who idolises legendary guitar player Ernesto de la Cruz and wants to learn how to play as well as he could. So he goes on a transformative odyssey of self-discovery into the realm of the dead to find his long-deceased idol and learn some lessons about the nature of creativity and originality. Whether it can reach the heights of Pixar’s 2015 masterpiece Inside Out remains to be seen, but Coco should surely be a feast for the eyes. Released November 15 in France, November 22 in the US, Croatia and the Philippines, and November 30 in Israel. (Credit: Disney-Pixar)

Pregnancy symptoms during week 4

No symptoms?

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.

Tender, swollen breasts

Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.

Fatigue

For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.

Nausea or vomiting

Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Pregnancy checklist at 4 weeks pregnant

Take a pregnancy test

If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.

Make a prenatal appointment

If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.
