Aguilera says she's struggling since divorce filing

Christina Aguilera says she has been struggling emotionally since separating from her husband and then filing for divorce last week.

"It's not easy, and there have been a lot of tears and sadness," she told Redbook magazine, in excerpts from the December issue posted online Thursday. "It's impossible to redefine yourself and your life overnight. Thankfully, I have my mom and a small group of close friends who are there for me 24/7 and whom I can trust and depend on. On days when it feels impossible to even get out of bed, much less function as a mother, their support and encouragement have kept me moving forward."

She and husband Jordan Bratman, who married in 2005, have a son, Max, who turns 3 in January.

Though telling the magazine she and music-industry executive Bratman, 33, had attended couples therapy, Aguilera, 29, otherwise declined to discuss their issues, saying, "Out of respect for my husband, I prefer to keep the specifics private. Right now, I'm just trying to figure out how to make it through each day."

Photographs posted Thursday by RadarOnline.com show Aguilera with a bruised right cheek and a cut below her lip.

The celebrity-gossip site said she went to the emergency room of Los Angeles' Cedars-Sinai Medical Center on Oct. 12, the day she and Bratman announced their separation, sparking speculation of possible domestic violence.

"Christina was bleeding from her mouth and had a bit of a busted lip," a source told the site. "Jordan told the nurses she had fallen down."

TMZ.com, however, says sources close to Aguilera confirm that her injury were indeed a result of "a simple fall."
