Christina Aguilera is rebounding – discreetly – from the collapse of her marriage to Jordan Bratman。

　　The superstar singer, 29, has quietly been seeing Matthew D. Rutler, a set assistant from her upcoming movie Burlesque – whom she tried to hide from the cameras Friday when they enjoyed a double date at SoHo House in Los Angeles with friends Nicole Richie and Joel Madden。

　　A friend tells PEOPLE that the relationship with Rutler started as a friendship, then turned into something more。

　　目前看来，刚刚恢复单身的乐坛天后克里斯蒂娜已经从婚姻破裂的伤痛中走了出来。这位二十九岁的歌手近期频繁被目击与一男子出双入对，疑似“新欢”曝光。据媒体报道，这位名叫马修-D-鲁特勒即是克里斯蒂娜的新片《滑稽表演》的幕后工作人员。由此看来，两人在工作中日久生情的可能极大。

　　"It's not serious yet, but it's something she is exploring and finding comfort in," the friend says. "It's new and she’s taking it day by day. She and Jordan were having problems for a long time. What kept them together is their love for their son. She met [Matthew] on set and, during a difficult time, leaned on as a friend. After she and Jordan separated, the friendship turned romantic."

　　The friend adds that Aguilera's son Max, who'll be 3 in January, is still the singer's No. 1 priority. "Being a great mom to Max is the most important thing in her life," says the friend。

　　有知情人士透露，两人的关系起初始于普通朋友，而后又有了更进一步的发展。“目前这段感情看起来还没有那么认真，这可能只是他聊以慰藉的寄托罢了。”天后身边的一位朋友告诉媒体，“她目前正在逐步习惯新生活，她与前夫的问题已经不是一天两天了，他们不断迁就对方都是为了儿子麦克斯着想。她在最艰难的时刻中，在片场认识了马修，刚开始只是普通朋友，在与前夫分手之后，‘友情’逐步升级成了‘爱慕’”。
