Jessica Biel shows off post-baby body in rare public appearance with brother

Jessica Biel showed off her post-pregnancy physique as she made a rare public appearance at a fashion event in Santa Monica Thursday.

The 33-year-old actress, who is married to Justin Timberlake, stepped out with the other Justin in her life -- her 30-year-old brother Justin Biel, the man behind the event.

The brunette beauty stunned in a stylish Self Portrait jumpsuit that consisted of wide leg cropped blue pants and a sheer black crocheted lace high neck top.

The new mom's four-month-old son Silas Randall was at home, giving her a well-deserved break.

As her singing spouse was not by her side, we assume he was busy at home on daddy duty.
