Taking a late night flight back from the Big Apple, Ashlee Simpson and her son, Bronx, arrived into LAX Airport on Tuesday night (April 24).

The singer/songwriter looked casually chic in grey skinny jeans, black sunglasses and a grey fedora while her little guy nuzzled his head into her shoulder rocking mini Converse sneakers and a matching grey and black ensemble.

The 27-year-old mommy and her adorable 3-year-old made the cross country trip to visit her boyfriend, Vincent Piazza, who has been in NYC filming scenes for "Boardwalk Empire".

Simpson, who has already been mastering the maternity role since 2008, is looking forward to becoming an aunt. As previously reported by GossipCenter, Ashlee's sister, Jessica Simpson, is pregnant with her first child and due at any time.

In a recent interview, the "Little Miss Obsessive" songstress expressed her excitement about her sister's pregnancy, saying, "I'm definitely excited. She's amazing. She will be such a good mommy."
