Jessica Simpson has paid tribute to her "soulmate" Ashlee Simpson Ross.
The ‘Dukes of Hazzard’ star has thrown a baby shower to celebrate the impending arrival of her nephew – Ashlee’s unborn son with husband Evan Ross – and Jessica paid a glowing Instagram tribute to her sibling.
The 40-year-old singer shared a picture of herself and Ashlee with the caption: "Celebrating the new life with my soulmate, best friend, role model, baby sis @ashleesimpsonross. This lady right here is someone we should all aspire to be… determined, hilarious, artistic, loving, soulful, wise, loyal and a champion of motherhood!!!(sic)"
And the mother-of-three praised her sister for managing to stay in shape during her pregnancy.
Jessica added: "I keep telling her that I looked like this 2 months pregnant. When she needs a good laugh I send her pics of my 3rd pregnancy journey! I love you and I can’t wait to be an auntie of 3!(sic)"
Ashlee – who also has son Bronx, 11, with former husband Pete Wentz and daughter Jagger, five, with Evan – also shared photos from the event.
She was joined by Jagger, Jessica and her daughters Maxwell and Birdie, and their mother Tina Simpson.
The 35-year-old star captioned the images: "I’m so grateful to be with my family as we get ready for my baby boy! Not long now! Thank you @tinasimpsonofficial @whambamevents for making my baby shower so special!!!
Ashlee had announced in April that she was expecting her third child and a source revealed at the time that she and Evan had been keen to expand their brood.
The insider said: "Ashlee has been wanting another baby for a long time. They always wanted a big family!"
