Big Bang Theory star Simon Helberg stepped out in L.A. Thursday, showing off his latest, greatest project to date: his first child with his love of nearly a decade, Jocelyn Towne.

Helberg's wife gave birth to the couple's daughter, Adeline, May 8.

"The family is thrilled," a source told Us Weekly of the proud new parents at the time, adding that Helberg, 31, channeled his Big Bang Theory character prior to welcoming Adeline -- by doing lots of research.

"Simon is excited to be a father," the source shared. "He's been doing his reading!"

The Let Go actor met Towne in Los Angeles; they dated for several years before making it official in a 2007 ceremony. Currently, they reside in Charlie Sheen's former Hollywood estate, which they purchased from the actor for $3 million last November.

上周四，31岁的《生活大爆炸》（Big Bang Theory ）男星西蒙·赫尔伯格（Simon Helberg）携相爱近10年的妻子乔思林·唐恩（Jocelyn Towne）和他的“最新成果”宝贝女儿一同出行。

可爱的小宝贝艾德林（Adeline）于5月8日降生，是这对夫妻的第一个孩子。

据知情人士透露，他们小两口开心极了。就同经常做实验的霍华德一样，西蒙为迎接女儿也做了很多研究工作。

“升级做爸爸让西蒙特别激动。他看了好多相关书籍呢！”

西蒙和乔恩林在洛杉矶相遇，相恋多年后于2007年正式结婚。去年11月，这对夫妇在好莱坞购下原查理·辛（Charlie Sheen）所有的房产，花费三百万美金。现在他们一家三口幸福的生活在这里。
