More news on this. It appears she does have a husband.

Suleman said she was concerned about her daughter's homecoming because her husband, a contract worker, is due to return to Iraq.

From the LA Times-
The mother of a woman who gave birth on Monday to octuplets said her daughter already has six children at home and was undergoing fertility treatment.

The Los Angeles Times reported on Thursday that Angela Suleman said her daughter had the embryos implanted last year, resulting in the eight births.

"They all happened to take," Suleman told the Times.
According to an earlier report, she did not show up at Kaiser until she was close to 12 weeks along. So they did not implant the embryos.

My question - what doctor in his/her right mind would treat a woman for infertility when she had undergone 5 pregnancies, resulting in 6 children over the previous 6 years?
