Ashlee Simpson-Wentz is supporting her newly single sister Jessica on Twitter.
"Everyday you move me to be a better person. I love you..miss u so much," Ashlee wrote Tuesday to Jessica, who has been in Japan filming her new VH1 series, The Price of Beauty. "You are a perfect friend and sis. Thank you."
Tony Romo dumped Jessica on the eve of her 29th birthday in July, causing her to cancel a Barbie and Ken-themed party. (Still, mom Tina said last week the family "still likes" him.)
"Les Miserables 'On My Own' -- can't sing this song without u ever. But it's my fav!" added Ashlee. The Broadway tune includes lyrics: "Pretending he's beside me / All alone, I walk with him till morning."
Jessica appreciates that her sis has her back. "I could never imagine getting thru the day without the love we share. I feel so far away!! Just wanna have pillow talk," she posted on Twitter in response.
