Ashley Tisdale & Haylie Duff Bike Around The Block

Ashley Tisdale and Haylie Duff share a laugh as they bike around their neighborhood on Sunday afternoon in Toluca Lake, Calif.

The twosome were both thrilled to hear the news that Haylie‘s younger sister Hilary is expecting her first child with husband Mike Comrie.

“So excited for @HilaryDuff and Mike!” Ashley tweeted once the news was out.

Soon to be aunt Haylie added, “Congrats to my sissy @HilaryDuff and my B.I.L Mike on their 1 year anniversary and the tiny new addition :)”

We’re sure Ashley is giving Haylie tips on being the best spoiling aunt she can be!
