Mischa Barton, Super Girl Candidates

Leggy blonde beauty Mischa Barton, 20, insists that rampant rumors of an engagement to boyfriend Cisco Adler are not true.

Just 18 months ago, Whitestarr rocker Adler was engaged to Rod Stewart's daughter, Kimberley, who said of new fiance at the time:

"He's my best friend, my lover, my soulmate - he really is my everything." She even had a tattoo done, declaring her love for Cisco and her rock star dad, saying: 'Daddy's Little Girl Loves Cisco'.

What does this mournful looking guy have that we don't know about?

According to published reports, the OC star and her rocker beau have only been dating for five months, but everyone nonetheless can't leave the subject of impending nuptials alone.

Adler says, "It (an engagement) is not true. The love is young!"

The Whitestarr lead singer is said to be wearing a lock necklace that only Barton has the keys to, which she wears around her neck.

In recent news, the lovely Mischa's career is looking to the heights, as she is apparently at the top of a list of candidates to bring Supergirl back to the big screen.

"If Superman Returns does as well as expected this summer then Supergirl will be pushed into the schedule," reveals one movie insider. "There are a few actresses in the reckoning and Mischa is at the top of that list." postchronicle
