A quick reference table covering the essential biographical details drawn from verified entertainment databases and media reports.

Who did Alexis Knapp have a baby with?

Alexis Knapp and actor Ryan Phillippe share a daughter named Kailani Merizalde Phillippe Knapp, who goes by Kai. Born on July 1, 2011, Kai is their only child together, as confirmed by People magazine.

When was her daughter born?

• Kai was born July 1, 2011 — making her 13 in 2024 and 14 in 2025 (People).
• Knapp was 21 at the time of birth, just a month shy of her 22nd birthday (IMDb).
• Ryan Phillippe, who was 36 at the time, has three children total: two with Reese Witherspoon and Kai with Knapp (People).

The implication: Knapp became a mother very early in her Hollywood career — just as her biggest break was about to hit theaters.

Is Ryan Phillippe still with Alexis Knapp?

No — Ryan Phillippe and Alexis Knapp are not together. Their relationship, which began in 2010 when they met on the set of The Mortician, ended sometime around 2011, before or shortly after their daughter’s birth, according to TV Insider.

Are Alexis Knapp and Ryan Phillippe still together?

• The relationship lasted roughly one year — from 2010 to 2011 (Yahoo Lifestyle).
• Phillippe has since been linked to several other partners, including actress Paulina Slagter (New York Post).
• Both are described as co-parents of Kai, with Phillippe sharing a rare photo of her on Instagram in 2023 (Instagram).

The pattern: Short-term relationships can have lasting family consequences.

Was Alexis Knapp in Pitch Perfect 3?

Yes — Alexis Knapp reprised her role as Stacie Conrad in Pitch Perfect 3 (2017), marking her final credited film appearance to date (IMDb).

What role did Alexis Knapp play in Pitch Perfect?

• She played Stacie Conrad, a member of the Barden Bellas, across all three films (Wikipedia).
• Stacie was known for her comedic timing and physically confident humor — a fan-favorite supporting character.
• Knapp also appeared in Project X (2012) and The Mortician (2011) during the same period (All American Speakers).

Why did Pitch Perfect 3 flop?

• The film grossed $185 million worldwide against a $45 million budget — lower than the second film’s $287 million (IMDb).
• Critical reception was mixed, with a Rotten Tomatoes score of 53%.
• Audience fatigue with the franchise formula was widely cited by reviewers.

The catch: The decision to leave Hollywood came at the peak of franchise recognition, not after a decline.

How old is Alexis Knapp’s daughter?

Kai was born on July 1, 2011, which makes her 14 years old as of 2025 (Famous Birthdays). Outlets in 2023 described her as 12 at the time (People), consistent with that timeline.

How old was Alexis Knapp when she had her baby?

• Knapp was 21 years old when she gave birth — turning 22 just 30 days later (IMDb).
• Ryan Phillippe was 36 at the time — a 15-year age gap.
• Knapp had just begun landing major film roles when she became a single mother.

What this means: Knapp navigated early motherhood alongside the peak of her Hollywood visibility — a rare and demanding combination in the entertainment industry.

Why did Reese leave Ryan Phillippe?

Reese Witherspoon and Ryan Phillippe divorced in 2007 after seven years of marriage. Reports at the time cited infidelity and the pressures of dual Hollywood careers as contributing factors (New York Post).

Why did Reece and Ryan split up?

• Witherspoon filed for divorce in 2006, citing irreconcilable differences.
• Phillippe’s reported relationship with Knapp in 2010 came three years after that divorce was finalized.
• The timeline shows a clear gap: Witherspoon (2007 divorce) → three-year break → Knapp (2010 relationship).

The pattern: Phillippe’s relationship with Knapp fits into a broader post-divorce chapter of his personal life, not a direct overlap with his marriage to Witherspoon.

“The widely repeated public narrative is that Phillippe and Knapp split after a short 2010 relationship before Kai’s 2011 birth.”
— Yahoo Lifestyle

“People reported that Kai was welcomed on July 1, 2011.”
— People magazine
