Another possiblity is that many of the women in Hollywood wait to have babies in their late 30s/early 40s. By that time, it is much more common to double or even triple ovulate.
It is also a time when you are much more likely to need assisted fertility, due to age.
Women coming off years of ovulation-suppressing birth control pills will also superovulate. My SIL had fraternals right after 8 years on the pill.
